How Your Nervous System Works & Changes

This Huberman Lab Podcast episode focuses on the nervous system, explaining its components and functions. The speaker, Andrew Huberman, details the system's five key actions: sensation, perception, feelings/emotions, thoughts, and actions, emphasizing the interplay between reflexive and deliberate processes. He highlights the role of neuromodulators like dopamine and serotonin in emotional states and explains neuroplasticity as a two-phase process requiring both focused effort (inducing agitation) and subsequent rest (sleep and non-sleep deep rest) for neural changes to occur. Listeners gain an understanding of how to leverage 90-minute ultradian rhythms for optimal learning and focus.
