PSYCH 011: Intraneuronal Signalling

Clinical Deep Dives · May 25, 2026 · 1h

While synapses transmit signals between neurons, the real transformation happens within. This chapter explores intraneuronal signalling - the complex cascade of intracellular processes that determine how a neuron responds to incoming information.

In this episode, we move inside the neuron to examine how signals are not simply received, but interpreted. Neurotransmitters bind to receptors, triggering intracellular pathways involving second messengers, protein kinases, and gene transcription. These cascades shape everything from immediate responses to long-term changes in structure and…
