- 0:00Speaker 1: Brought to you by Toyota. Let's go places. Welcome to
- 0:05Speaker 1: Stuff you Should Know from house stuff Works dot com. Hey,
- 0:14Speaker 1: and welcome to the podcast. I'm Josh Clark, There's Charles W.
- 0:17Speaker 1: Chuck Bryant, and this is stuff you should know the podcast.
- 0:21Speaker 1: Greetings pricklings. Hello, everyone, brains, brains, brains. That's right, that's
- 0:27Speaker 1: my intro. Uh that you didn't do it ten times though?
- 0:31Speaker 1: About no one wants to hear that. And we're not
- 0:33Speaker 1: going to even talk about ten brain myths we even
- 0:36Speaker 1: though the this episode is called ten Myths about the Brain. Yeah,
- 0:40Speaker 1: if you're new to the show and you've never heard
- 0:42Speaker 1: us do one of our famous top tens, then you
- 0:46Speaker 1: probably don't know. We rarely cover all ten. We will
- 0:49Speaker 1: tease you a bit with six to eight and then
- 0:52Speaker 1: say go read the article if you want the other one.
- 0:54Speaker 1: And in this case, we've actually covered a couple of
- 0:56Speaker 1: the things before, so there's no point in rehashing exactly
- 1:00Speaker 1: so that. I guess I just probably need to explain
- 1:02Speaker 1: that you laid the ground rules pretty well man to
- 1:05Speaker 1: a top ten that is really not tin um. So
- 1:08Speaker 1: we we have brains in our heads. Uh, And I
- 1:12Speaker 1: think most people walk around feeling like they have some
- 1:15Speaker 1: ideas about the brain, some understanding, um, but it turns
- 1:19Speaker 1: out that some of them are wrong. There's myths out
- 1:21Speaker 1: there and so have kind of interesting weird origins too. Yeah.
- 1:26Speaker 1: I thought this is pretty cool article because we've covered
- 1:28Speaker 1: the brain a lot and it's one of our favorite,
- 1:30Speaker 1: favorite favorite subjects. So it's kind of cool to root
- 1:34Speaker 1: out some of these things that a couple of these
- 1:35Speaker 1: I thought were true. Well. Well, for example, like, um,
- 1:39Speaker 1: your brain is gray, I thought that to be true. Well,
- 1:43Speaker 1: and it's understandable why too, because people call the brain
- 1:47Speaker 1: gray matter. Um apparently Hercule Paul row I just said
- 1:53Speaker 1: that like a dog that was That was right, h
- 1:56Speaker 1: That's an odd name to have to say though. Yeah,
- 1:58Speaker 1: Hercules plaically especially from my tongue marble mouth. He used
- 2:03Speaker 1: to call his brains his gray cells. Oh yeah. Um,
- 2:07Speaker 1: so yeah, everybody thinks the brain is great and it
- 2:10Speaker 1: is gray. There are very much, um lots of gray
- 2:13Speaker 1: areas called gray matter, but there's other colors to the
- 2:16Speaker 1: brain too. Yeah. This kind of knocked me out because
- 2:19Speaker 1: I had no idea that the brain was also white, black,
- 2:23Speaker 1: and red like our Georgia bulldogs in Atlanta, falcon starts
- 2:27Speaker 1: lapping in there, everybody's brains walking around the bulldog fan So,
- 2:30Speaker 1: like you said, there is a lot of gray matter,
- 2:32Speaker 1: uh cells, neurons connecting to each other. There's also white matter.
- 2:37Speaker 1: Well that's the stuff that connects them. Well, the white
- 2:40Speaker 1: matter is is the nerve fibers right right, So it
- 2:42Speaker 1: connects like your gray matter regions to one another. So
- 2:46Speaker 1: that makes sense. Yeah, but what about the substantia nigra
- 2:51Speaker 1: Latin for black substance that is part of your brain
- 2:56Speaker 1: is black? I would think that would be scary. Yeah,
- 2:58Speaker 1: he was dead, dude, think so. But the that that
- 3:01Speaker 1: region of the brain um, it has to do with
- 3:03Speaker 1: motor control, like fine control, and that's that They think
- 3:07Speaker 1: that possibly that's where Parkinson's damage comes from, or Parkinson's
- 3:10Speaker 1: disease is located there. And the reason it's black is
- 3:13Speaker 1: because of neuromelanin, which is a pigment. And I was
- 3:17Speaker 1: very curious why your brain would eat any kind of pigment? Whatsoever?
- 3:20Speaker 1: Did you get to that? Yeah, it turns out they
- 3:22Speaker 1: don't know, but they think that it basically takes um
- 3:27Speaker 1: it removes heavy metals from your bloodstream. From that area
- 3:31Speaker 1: and that they they also think that it has to
- 3:33Speaker 1: do with there's a adrene of chrome, do you remember that?
- 3:38Speaker 1: From Fear and low thing in Las Vegas. So that
- 3:41Speaker 1: stuff is real, and your brain produces as a byproduct
- 3:44Speaker 1: of some of his normal processes, and we would all
- 3:47Speaker 1: be totally psychotic apparently from the stuff if it wasn't
- 3:50Speaker 1: for neuromelanin. They think basically getting rid of it. So
- 3:53Speaker 1: we depend on that color. Yeah, that pigment, at least
- 3:57Speaker 1: not for coloring in this case, but some other stuff. Yeah,
- 4:00Speaker 1: I couldn't. The reason we think gray besides people calling
- 4:03Speaker 1: it gray matters because usually when we see a brain
- 4:05Speaker 1: it's floating in a jar, then it has been turned
- 4:08Speaker 1: gray from the formaldehyde and stuff. But I couldn't find
- 4:11Speaker 1: any kind of picture of like an active brain with
- 4:15Speaker 1: all these colors. I guess it's impossible unless they just,
- 4:19Speaker 1: you know, peel your skull off and take a picture
- 4:22Speaker 1: real quick. Yeah, I'm sure that was exist. What couldn't
- 4:25Speaker 1: I find a picture? I don't know. I mean, yeah,
- 4:27Speaker 1: they do brain surgery, you know, with the healthy living brain.
- 4:33Speaker 1: Didn't work super hard though, that's the secret. So there
- 4:36Speaker 1: there you go. Red black, white and gray your brain,
- 4:39Speaker 1: all right. Number two, listening to Mozart makes you smarter. Yeah,
- 4:44Speaker 1: this one I thought was did too, because Baby Einstein
- 4:48Speaker 1: if you've never heard of that, that is, parents are
- 4:50Speaker 1: living this stuff, big, big, multimillion dollar industry of packaging
- 4:56Speaker 1: classical music and poetry and stuff like that to a
- 5:01Speaker 1: not just to your baby and toddler and growing child,
- 5:04Speaker 1: but for your fetus as well. Even. Yeah, the Mozart
- 5:08Speaker 1: effect is what it's called, UM, and it's gonna be smarter.
- 5:11Speaker 1: Apparently the Mozart effect is trademarked by a guy named
- 5:15Speaker 1: Dan Campbell. Basically, UM puts together Mozart and CDs and
- 5:20Speaker 1: books and stuff like that. Um. The thing is is
- 5:23Speaker 1: this Mozart effect was It was first noted in the fifties,
- 5:27Speaker 1: I think by an ear nose and throat doctor named
- 5:29Speaker 1: Albert Tomattus, and he said that he made it. He
- 5:36Speaker 1: said that UM, the his patients who were struggling with
- 5:40Speaker 1: speech and audit auditory disorders UM showed improvement when they
- 5:45Speaker 1: listened to Mozart specifically. And then in the nineties somebody
- 5:49Speaker 1: else apparently conducted a test at the University of California,
- 5:53Speaker 1: Irvine that showed that people's IQ scores improved after listening
- 5:58Speaker 1: to Mozart, and then the Mozart effects was born. Well,
- 6:02Speaker 1: so based on these studies, I would think that it
- 6:05Speaker 1: does make you smarter. So is that true? Apparently not
- 6:09Speaker 1: necessarily no, because these are all myths. Yeah, that that
- 6:12Speaker 1: that you see Irvine study in particular was kind of
- 6:15Speaker 1: taken out of context. I get the impression, and um,
- 6:20Speaker 1: they were saying, well, we never said it makes you smarter.
- 6:22Speaker 1: We just said that it improved people's ability on the
- 6:26Speaker 1: specific temporal spatial test. Yeah, this one specific thing. We
- 6:31Speaker 1: didn't say it makes you smarter. That's the popular media
- 6:34Speaker 1: that did that. So things got a little twisted around
- 6:36Speaker 1: over time, and since then they have not been able
- 6:40Speaker 1: to duplicate these results from that original test. So it
- 6:44Speaker 1: turns out it probably won't hurt you any right, but
- 6:46Speaker 1: listening to classical music is not going to actually make
- 6:48Speaker 1: you smarter. But they have found that, um, learning to
- 6:52Speaker 1: play music, you can do a lot of stuff. Um,
- 6:57Speaker 1: it improves concentration, self constant competence, coordination. Really yeah uh
- 7:01Speaker 1: and you mentioned people playing Mozart to get the Mozart
- 7:05Speaker 1: effect for their fetuses. Yeah, Um, have you ever heard
- 7:08Speaker 1: the one that you get a new wrinkle in your
- 7:10Speaker 1: brain every time you learn something. I knew that wasn't true.
- 7:14Speaker 1: It sounds a little bit like an angel gets his
- 7:16Speaker 1: wings every time. All totally, Uh, that is not true.
- 7:19Speaker 1: But there are some cool little factoids in here. Uh,
- 7:24Speaker 1: one of which is that by the time you reach
- 7:27Speaker 1: forty weeks old, you have the same brain. It will
- 7:30Speaker 1: get larger, of course, but you have all the same
- 7:33Speaker 1: little folds and crevices called jerry and sulci um, all
- 7:39Speaker 1: folded up together. And the reason it's folded up together
- 7:42Speaker 1: is because our brain is large and the skull isn't,
- 7:47Speaker 1: so it needed to scrunch itself in there as we evolved.
- 7:51Speaker 1: And I think if you unfolded all that, the brain
- 7:54Speaker 1: would be the size of a tennis court. No, no,
- 7:56Speaker 1: that's the intestines a pillowcase. Okay, that's still pretty Yeah,
- 8:00Speaker 1: it's huge. Um, and that's why we're so smart. Um,
- 8:05Speaker 1: which kind of leads us to another. Um. Another myth
- 8:09Speaker 1: all right, that humans have the biggest brain, which is
- 8:13Speaker 1: not the case, which makes sense to me. I thought
- 8:16Speaker 1: this one was pretty cool. Actually, Um, A lot of
- 8:19Speaker 1: people walking around I think that because we're so smart,
- 8:22Speaker 1: we must have the biggest brain. But if you if
- 8:24Speaker 1: you think about it, no, a whale is going to
- 8:26Speaker 1: have a bigger brain than a human brain. That's true
- 8:28Speaker 1: because whales are enormous. Our brains about three pounds a whale.
- 8:33Speaker 1: Sperm whales about what's seventeen pounds, Yeah, which is a
- 8:36Speaker 1: huge brain. So why aren't sperm whales running the planet?
- 8:40Speaker 1: The reason why, It doesn't really matter the size of
- 8:43Speaker 1: the brain. It's the size of the brain to the
- 8:45Speaker 1: rest of the body. That ratio is what matters. Yeah,
- 8:48Speaker 1: I thought that was super interesting. They used dolphins as
- 8:50Speaker 1: an example because the dolphin's brain is about the same
- 8:53Speaker 1: size of a humans brain. Dolphins are super smart, But
- 8:57Speaker 1: an average dolphin weighs about three fifty pounds. Uh, I
- 9:01Speaker 1: don't know. Does it say how much the average adultways,
- 9:03Speaker 1: it's not three. I would say, depending on whether it's
- 9:06Speaker 1: male or female, anywhere between a hundred to two hundred pounds,
- 9:09Speaker 1: whether or not average somewhere in there. Sorry. Uh. And
- 9:15Speaker 1: then they also go on to name some other animals,
- 9:18Speaker 1: which was just sort of cute to think about. A
- 9:20Speaker 1: beagle's brain is two point five ounces. Cute, little beagle
- 9:25Speaker 1: and a sparrow has a brain that weighs less than
- 9:28Speaker 1: half an ounce. That's adorable. So again though it's the
- 9:31Speaker 1: it's the brain size to body size ratio, and humans
- 9:34Speaker 1: it's one to fifty UM. Most other mammals it's one
- 9:38Speaker 1: to one eight UM, and then in birds it's one
- 9:41Speaker 1: to two twenty typically. Yeah, but we do have humans
- 9:45Speaker 1: compared to mammals, we have the largest cerebral cortex, which
- 9:48Speaker 1: is really where like that's the money section. It's also
- 9:51Speaker 1: the newest part of our brain. It's on the outermost surface, um,
- 9:54Speaker 1: and that's where all the higher functions are carried out.
- 9:56Speaker 1: And that's what really separates us. That's why we run
- 9:59Speaker 1: the planet. Otherwise just be orangutans. Um. What about subliminal
- 10:04Speaker 1: messages and we learn from those? Uh, that is a falsehood, sir.
- 10:10Speaker 1: I guess that's the spoiler. All these are false but
- 10:13Speaker 1: their myths. Yeah, they're myths. Um. But back in the
- 10:16Speaker 1: nineteen fifties, there was a marketing executive, a researcher named
- 10:20Speaker 1: James Vickery who, uh did you know everyone always heard
- 10:24Speaker 1: you know, you go to the movies and they splash
- 10:25Speaker 1: up Coca cola and popcorn. I thought that was a myth.
- 10:29Speaker 1: I did too, but that was true. They did that
- 10:30Speaker 1: in nineteen fifty seven. Yeah, there's a there's a still
- 10:33Speaker 1: in this article from the movie and over Kim's face
- 10:39Speaker 1: it says hungry eat popcorns and it's from a frame
- 10:41Speaker 1: of the movie. So that's one three thousandth of a second.
- 10:45Speaker 1: And um, Vickery said, you know what, Uh, sales increased
- 10:49Speaker 1: in the theater by eighteen percent for popcorn I'm sorry
- 10:53Speaker 1: for drinks, and by fifty seven percent for popcorn thanks
- 10:57Speaker 1: to these messages. Yeah, and everybody said, okay, well, we're
- 11:01Speaker 1: very interested in basically psychologically manipulating everybody into buying our products.
- 11:06Speaker 1: So they started putting that stuff in jingles and in
- 11:09Speaker 1: UM movies and television, and UM, they found pretty quickly
- 11:15Speaker 1: that it actually doesn't have an effect yet. Well, they
- 11:18Speaker 1: banned it first of all, the FEC band in nine,
- 11:22Speaker 1: because they did think it worked at the time. UM.
- 11:25Speaker 1: But then later on it turns out that James Vickery
- 11:29Speaker 1: just lied about the results, not true at all. He's like, hey,
- 11:33Speaker 1: I was a sales guy, not a scientist, but you
- 11:35Speaker 1: expect uh so yeah, like you said, the FEC band
- 11:40Speaker 1: subliminal advertising in general, which was a good move because
- 11:43Speaker 1: if it did work, that's not okay. No, but a
- 11:47Speaker 1: lot of people still think that it's still around and
- 11:49Speaker 1: then it actually does work, Yes, but it is not true.
- 11:52Speaker 1: And they even tested this in Canada evidently on TV.
- 11:55Speaker 1: They flashed the message call now during a broadcast, and
- 11:59Speaker 1: I guess nobody called. Maybe they didn't give a number.
- 12:03Speaker 1: There's this right, I feel like I need to call somebody,
- 12:06Speaker 1: but I don't get it. I wondered though, like if
- 12:09Speaker 1: if they were studying the wrong thing, like call now
- 12:13Speaker 1: makes sense, but what if it has to be much
- 12:15Speaker 1: more explicit, like hungry eat popcorn? You can't eat popcorn?
- 12:21Speaker 1: Like maybe that would make you grab a bite of
- 12:23Speaker 1: popcorn fit we're in your lap. Maybe it has to
- 12:25Speaker 1: be more direct, like hungry, go buy popcorn at the
- 12:28Speaker 1: front concession stand now, you know, because then your brain
- 12:34Speaker 1: would obey that command rather than a roundabout command that's
- 12:37Speaker 1: the result of something you have to do, telling you
- 12:39Speaker 1: to go do that thing. Maybe that would work. So
- 12:41Speaker 1: you're leaving the door open for this for further testing.
- 12:43Speaker 1: I could see it subliminal below the lineman or lemon,
- 12:49Speaker 1: which is the threshold of our conscious awareness. Yeah, it
- 12:54Speaker 1: looks like Lineman when by itself, that's what's in sprit.
- 12:57Speaker 1: But if he said subliminal, then somebody would just on
- 13:00Speaker 1: two upside the head, you know. Yeah, where are we now?
- 13:04Speaker 1: We are on the idea that brain damage is always permanent.
- 13:08Speaker 1: I didn't know that this was a thing. I didn't
- 13:10Speaker 1: know that people said that. Sure, I never heard that. Well,
- 13:14Speaker 1: I think the point of it is is you know
- 13:16Speaker 1: that the brain can't repair itself once it's damaged, And
- 13:20Speaker 1: that's absolutely not true. It's not true. The brain is
- 13:23Speaker 1: extremely resilient. It's it's so much so that there's this
- 13:27Speaker 1: thing called plasticity, um, which is it kind of ties
- 13:31Speaker 1: into that idea that you get a new wrinkle when
- 13:33Speaker 1: you learn something that's not true. But your brain can
- 13:37Speaker 1: rewire itself. That's how you learn and unlearned behaviors through
- 13:41Speaker 1: brain plasticity. Yes, so I guess there are some truth
- 13:44Speaker 1: in that. Neurons, once they are damaged, they cannot grow back, right,
- 13:48Speaker 1: but thanks to plasticity, that will make new neural connections
- 13:52Speaker 1: in sometimes surprising ways, which is why if you've had
- 13:57Speaker 1: a stroke and damage part of your brain, you can
- 13:58Speaker 1: relearn to speak alps if you've lost that ability by
- 14:01Speaker 1: forging these new connections. There's a girl out there, um
- 14:04Speaker 1: who has only one hemisphere of her brain. That's it
- 14:08Speaker 1: that way. I don't remember she was born that way
- 14:10Speaker 1: or if it was the result of surgery or damage
- 14:12Speaker 1: or something, but she's got half of a brain. Her
- 14:15Speaker 1: brain has just one hemisphere, and she has binocular vision.
- 14:19Speaker 1: She can see out of both eyes, which they had
- 14:21Speaker 1: no idea how that was going on. And they finally
- 14:24Speaker 1: went in and looked, I guess using an m R
- 14:27Speaker 1: I and they found that her optic nerve that should
- 14:30Speaker 1: be connected to the missing hemisphere had basically grown, had
- 14:34Speaker 1: grown to go patch in another part of her brain
- 14:38Speaker 1: on the other side, and it basically hijacked this other
- 14:41Speaker 1: part of her brain and was using it for sight.
- 14:43Speaker 1: That is unbelievable. That's the brain. I wonder what you
- 14:46Speaker 1: lose though, I wonder if it forges a connection and
- 14:49Speaker 1: at the expense of another, you know what I'm saying, Yeah, like,
- 14:53Speaker 1: could she be like, man, I can see through both eyes,
- 14:55Speaker 1: but I can't tie my shoot any longer. Yeah, maybe, yeah,
- 14:57Speaker 1: it's possible, But I mean the brain would would say, well,
- 15:01Speaker 1: it's better you can see somebody else can tie your shoes.
- 15:04Speaker 1: Well that makes me wonder, though, I wonder if there
- 15:06Speaker 1: is an order to it all, like if the brain
- 15:09Speaker 1: knows what's more important. Yes, there is. As a matter
- 15:12Speaker 1: of fact, this ties into that idea that you only
- 15:15Speaker 1: use ten percent of your brain. Wow, all right, let's
- 15:18Speaker 1: hear it. Well that's not true, by the way, right,
- 15:21Speaker 1: And actually that one has a pretty interesting origin, doesn't it. Yeah,
- 15:25Speaker 1: they're not quite sure where it came from. Um, it
- 15:28Speaker 1: seems like it's always been around though, the notion that
- 15:31Speaker 1: you only use ten percent of your brain. But um,
- 15:33Speaker 1: they think it may have come from American psychologist William
- 15:37Speaker 1: James in the early nineteen hundreds when he said the
- 15:40Speaker 1: average person rarely achieves but a small portion of his
- 15:43Speaker 1: or her potential. And that was just sort of twisted
- 15:46Speaker 1: into ten percent of your brain is used. And people,
- 15:49Speaker 1: you know, you see people taking advantage of this notion
- 15:52Speaker 1: all the time with self help books like Tap into
- 15:54Speaker 1: the Other and it's just bunk, right, And this is
- 15:57Speaker 1: where it ties in. It is in that all regions,
- 16:03Speaker 1: all physical regions of your brain are being used. But
- 16:07Speaker 1: there's a theory that's around for savantism. Explain savantism, which
- 16:11Speaker 1: I want to do someday, we need to write the
- 16:13Speaker 1: article on it. But so fascinating. There's a theory right
- 16:19Speaker 1: now that savanta is um is from the result of
- 16:22Speaker 1: like brain damage. What what savantism is the result of
- 16:26Speaker 1: the brain's tyranny of the frontal lobe is what it's called.
- 16:31Speaker 1: And basically the idea is that your frontal lobe decides
- 16:36Speaker 1: what's important, and it bosses around all the other regions
- 16:39Speaker 1: of your brain to carry out this very smooth, efficient
- 16:43Speaker 1: streamline process that basically it decides is the most important,
- 16:48Speaker 1: and in doing so, it cast to the side a
- 16:51Speaker 1: lot of other stuff, like the ability to make great art,
- 16:54Speaker 1: or the ability to count a bunch of matches that
- 16:56Speaker 1: just fell on the floor, whatever, And that savantasm is
- 16:59Speaker 1: the result of this executive function, this tyranny of the
- 17:01Speaker 1: frontal cortex being disrupted, so that maybe you aren't just
- 17:06Speaker 1: the most efficient shark in the tank any longer, and
- 17:10Speaker 1: you're not out there and like going, going, going, and
- 17:12Speaker 1: like trying to compete and beat everybody else. But there's
- 17:16Speaker 1: all these other things that are now free to just
- 17:18Speaker 1: kind of blossom, like artistic deep, amazing, artistic, interesting abilities. Yeah,
- 17:24Speaker 1: that's that's this theory point and we're just now learning
- 17:27Speaker 1: this stuff. But it suggests that maybe we do only
- 17:31Speaker 1: use a portion of our abilities, not physical, like we're
- 17:35Speaker 1: using a dred percent of the physical parts of our brain,
- 17:38Speaker 1: but what we're using it for is that issue. Yeah,
- 17:40Speaker 1: you see what I'm saying. Yeah, yeah, so there's definitely
- 17:42Speaker 1: something to that. Yeah. I trip out on the brain
- 17:46Speaker 1: a lot, Like when I'm studying it for the podcast,
- 17:49Speaker 1: I'll get sidetracked. Like this morning, I was reading this
- 17:52Speaker 1: article and I just had one of those little flights
- 17:54Speaker 1: of fancy where it amazed me that I was looking
- 17:57Speaker 1: at these printed shapes on a pay paper that formed
- 18:01Speaker 1: words into sentences that I understood and had meaning. And
- 18:05Speaker 1: I just was amazed by the brain. Just laying in
- 18:08Speaker 1: bed this morning, I was like, oh my god, Like
- 18:10Speaker 1: I'm reading these words that makes sense, and I'm speaking
- 18:12Speaker 1: words that have a symbol form on a paper, And
- 18:16Speaker 1: I promise you I wasn't on LSD this morning, but
- 18:20Speaker 1: I just had one of those moments where it just
- 18:21Speaker 1: like totally amazed me that I was even able to read.
- 18:24Speaker 1: So the brain basically made you impressed with itself. Yes
- 18:28Speaker 1: it did. And while you mentioned ls do we I
- 18:31Speaker 1: guess we can say in passing apparently drugs do not
- 18:36Speaker 1: create holes in your brain. That is not true, um.
- 18:39Speaker 1: And there's a lot of uh back and forth over
- 18:42Speaker 1: how much damage drugs due to your brain at all,
- 18:46Speaker 1: how reparable that damage is. And there are studies going
- 18:50Speaker 1: on on all all the all the time about long
- 18:52Speaker 1: term drug use and the results. One of them, interestingly
- 18:57Speaker 1: found that they think that some long term use of
- 19:01Speaker 1: some drugs can cause structures in the brain to grow,
- 19:05Speaker 1: and that is why addicts may have a hard time
- 19:07Speaker 1: kicking the habit, because they've grown a certain part of
- 19:10Speaker 1: their brain. I guess to Yeah, your limbic system is
- 19:13Speaker 1: strengthened through that. Very interesting and alcohol um does not
- 19:19Speaker 1: kill brain cells. It damages the dentrides that we've talked about,
- 19:23Speaker 1: and those are the ends of the neurons where the
- 19:25Speaker 1: connections are taking place. I guess right. So it makes
- 19:29Speaker 1: your neurons talk sideways to one another like the brain
- 19:32Speaker 1: cells are still there, but they just can't talk about yeah,
- 19:35Speaker 1: pretty much. And there's something a neurological disorder called Wernikey
- 19:41Speaker 1: Corsicov syndrome, and that is uh can result in a
- 19:45Speaker 1: loss of neurons in the brain. But that's basically what
- 19:48Speaker 1: I think of when I think someone has like pickled
- 19:50Speaker 1: themselves with alcohol. But that's kind of what's going on.
- 19:53Speaker 1: It's actually not the alcohol that's killing brain cells. It's
- 19:57Speaker 1: from it's from a uh A deficiency and thymine. That amazing. Yeah,
- 20:03Speaker 1: So if if you have a thymine deficiency, you can
- 20:05Speaker 1: get this war Nikki Corsicov syndrome and um, that's a
- 20:09Speaker 1: B vitamin. And if you are an alcoholic, you typically
- 20:13Speaker 1: aren't absorbing your your thymin like you would if you
- 20:16Speaker 1: weren't an alcoholic, which is why it's associated with alcoholism.
- 20:18Speaker 1: But it's not alcohol killing brain cells, right, And it's
- 20:21Speaker 1: much easier for me just to say they've pickled themselves,
- 20:25Speaker 1: which is really sad. We're laughing, but it is. It
- 20:28Speaker 1: is super sad. Yes, it is. If you've ever met
- 20:31Speaker 1: anyone that was pickled, well, yeah, and here's a alcohol
- 20:33Speaker 1: Any addicts suffering as a result of their addiction is
- 20:36Speaker 1: extremely sad, it is. So that's all I got. How
- 20:40Speaker 1: many was that? Seven? Is eight or six and a
- 20:43Speaker 1: half something like that. Um, if you want to learn
- 20:46Speaker 1: the fate of the other remaining brain myths from this
- 20:50Speaker 1: top ten list. Type in brain myths in the search
- 20:54Speaker 1: bart how stuff works dot com and it will bring
- 20:56Speaker 1: this article up. And actually we sort of have issue
- 20:59Speaker 1: with one of them we left off was the decapitation.
- 21:03Speaker 1: They said it was a myth. I guess I didn't
- 21:05Speaker 1: even read it, kind of but didn't we say it was?
- 21:08Speaker 1: They say, and they're like, yeah, it's gonna last for
- 21:11Speaker 1: a couple of seconds or whatever, like, which is what
- 21:14Speaker 1: we said in the podcast. But for some reason they
- 21:17Speaker 1: made that seem like, but that's nothing right. But then
- 21:20Speaker 1: they said that it's an extremely painful way to die
- 21:23Speaker 1: because you are conscious. Afterwards, it was it was kind
- 21:26Speaker 1: of a cluster mixed messages. Yeah, all right, uh so
- 21:29Speaker 1: I said, such partians this time for a listener. Now, yes,
- 21:34Speaker 1: I'm gonna call this poop poopy time. We did our
- 21:39Speaker 1: our podcast on fecal transplants, and we've had all manner
- 21:43Speaker 1: of poopy emails coming in and I'm gonna share one
- 21:46Speaker 1: from Jacob Carnes, U, Hi, Josh, Chuck and Jerry and
- 21:50Speaker 1: he spelled Jerry right. I just finished the Fecal Transplant
- 21:53Speaker 1: podcast and felt compelled to write in after you mentioned
- 21:55Speaker 1: the Nora virus, which I was afflicted with about two
- 21:58Speaker 1: weeks ago. Didn't last long, just about twenty four hours,
- 22:00Speaker 1: but it hit instantly, like someone flipped the switch. I
- 22:04Speaker 1: will spare you the details, but it was nearly the
- 22:06Speaker 1: worst I've ever felt. The day after was nearly the
- 22:09Speaker 1: best I've ever felt, due to the euphoria of still
- 22:12Speaker 1: being alive. But for the following week, my gut felt
- 22:15Speaker 1: like it just wasn't right. My hunch is that it
- 22:17Speaker 1: was really messed with the internal flora. He needs some
- 22:20Speaker 1: Kombucha's that. Oh it's this um. It's just like fermented
- 22:25Speaker 1: basically like probiotic drink. Um. I guess it's Eastern. It's
- 22:31Speaker 1: really delicious. There's some very delicious kombucca drinks out there,
- 22:35Speaker 1: and it's supposedly promotes um colonization in your gut. You're
- 22:39Speaker 1: drinking this stuff. I love it. Yeah, where you get it?
- 22:42Speaker 1: Whole Foods has his kind. It's called GTS and they
- 22:46Speaker 1: have a specific flavor called ginger a. That's just it's
- 22:50Speaker 1: so good. You have to check that out. Yeah all right. Uh.
- 22:53Speaker 1: He follows up to say, this is my favorite part.
- 22:55Speaker 1: Like I said, I felt compelled to write after you
- 22:57Speaker 1: mentioned the Nora virus, but I felt obligated after you've
- 23:00Speaker 1: brought up the terror of your young selves experience when
- 23:04Speaker 1: you had the misfortune of using the bathroom after your
- 23:06Speaker 1: father's remember that old man poop. When I was a child,
- 23:10Speaker 1: my father liked to enjoy a cigarette while doing his
- 23:13Speaker 1: business is very seventies, So when I heard the call
- 23:18Speaker 1: uh shortly after him, I was subjected to the putrid
- 23:21Speaker 1: number two smell mixed with the stale cigarette smoke, and
- 23:25Speaker 1: to this day I have trouble separating the ladder from
- 23:27Speaker 1: the former. As I grew up, the need to look
- 23:30Speaker 1: cool convinced me to try and take up the habit
- 23:32Speaker 1: of smoking to look cool on the toilet numerous times. Uh.
- 23:36Speaker 1: But my childhood association has at least helped me come
- 23:39Speaker 1: to my senses. So you never learned to smoke because
- 23:43Speaker 1: he associated with his dad's poop. That's good. Whatever works.
- 23:47Speaker 1: Thanks for another great podcast, guys, Jacob Carnes. Yeah, I
- 23:51Speaker 1: guess for all of you smoking out there, like take
- 23:53Speaker 1: it to the toilet. See what happens. I take a
- 23:55Speaker 1: big whiff of poop. Well, while you're smoking a cigarette
- 23:59Speaker 1: and they'll probably bring Q of your habit mixing, disgusted
- 24:02Speaker 1: with anything. Well, we'll break you have habits right, Um,
