Clinical Deep Dives
Clinical Deep Dives is a Medlock Holmes podcast for clinicians and learners who want understanding, not just information. Using classic medical and surgical texts as a guide and the generative power of AI, each episode explores ideas with curiosity and clarity, designed for learning on the move and knowledge that actually sticks.

This chapter is not about a disorder, but about a way of seeing. The neuropsychiatric approach reframes the patient encounter as an integration of neurology…
Clinical Deep DivesPSYCH 031: Neuroscience of Substance Use Disorders
Substance use disorders are often misunderstood as failures of will. This chapter reframes them as disorders of brain systems governing reward, motivation…
Clinical Deep DivesPSYCH 030: Learning Theory and Psychosis, Anxiety, and Addiction
At its core, the brain is a learning system - constantly updating itself based on experience. This chapter explores how fundamental learning mechanisms, when…
Clinical Deep DivesPSYCH 029: Neuropsychiatry of Self
The sense of self feels immediate and unquestionable - yet it is a construction. This chapter explores the neuropsychiatry of self, examining how brain systems…
Clinical Deep DivesPSYCH 028: Functional Brain Connectivity and Psychopathology
The brain is not simply a collection of regions, but a network defined by how those regions communicate. This chapter explores functional connectivity - the…
Clinical Deep DivesPSYCH 027: Radiotracer Imaging with Positron Emission Tomography and Single Photon Emission Computed Tomography: Fundamental Principles, Methodology and Role in Neuropsychiatric Research
While MRI shows structure and EEG captures electrical activity, radiotracer imaging reveals something different: the brain’s molecular activity in action. This…
Clinical Deep DivesPSYCH 026: Electroencephalography in Psychiatry
If imaging reveals structure, electroencephalography (EEG) captures activity in real time. This chapter explores how electrical signals generated by neuronal…
Clinical Deep DivesPSYCH 025: Nuclear Magnetic Resonance Imaging and Spectroscopy: Basic Principles and Recent Findings in Neuropsychiatric Disorders

Clinical Deep DivesPSYCH 014: Chronobiology, Circadian Rhythm, and Psychiatry
The brain does not function in a constant state - it operates in rhythms. This chapter explores chronobiology and circadian systems, revealing how internal…
Clinical Deep DivesPSYCH 013: Immune–Brain Interactions in Psychiatry

Clinical Deep DivesPSYCH 011: Intraneuronal Signalling
While synapses transmit signals between neurons, the real transformation happens within. This chapter explores intraneuronal signalling - the complex cascade…
Clinical Deep DivesPSYCH 010: Neurotrophic Factors
Not all neural processes are about signalling in the moment. Some operate on a different axis entirely - governing growth, survival, and long-term adaptation…
Clinical Deep DivesPSYCH 009: Novel Neurotransmitters
For decades, psychiatry has centred on a core set of neurotransmitters - dopamine, serotonin, noradrenaline. Yet the brain’s chemical language is far richer…
Clinical Deep DivesPSYCH 008: Neuropeptides: Biology, Regulation and Role in Neuropsychiatric Disorders
Beyond fast neurotransmission lies a quieter, more sustained form of communication. Neuropeptides do not simply transmit signals - they shape the context in…
Clinical Deep DivesPSYCH 007: Biogenic Amine Neurotransmitters
If amino acid neurotransmitters set the basic tone of brain activity, biogenic amines shape its nuance. This chapter explores the neurotransmitter systems that…
Clinical Deep DivesPSYCH 006: Amino Acid Neurotransmitters

Clinical Deep DivesPSYCH 003: Functional Genomics of Human Brain Development
Before there are thoughts, emotions, or behaviours, there is a set of instructions - not fixed, but dynamic. This chapter explores how genes guide the…
Clinical Deep DivesPSYCH 002: Functional Neuroanatomy
If neuroscience asks how the brain works, functional neuroanatomy asks where those processes unfold. This chapter moves us from abstraction into structure —…
