028 The Thalamus and Hypothalamus

In this episode, Leslie Samuel discusses the thalamus and hypothalamus, two critical regions of the brain. The thalamus acts as a regulatory gateway for sensory input and motor output, while the hypothalamus is involved in homeostasis, emotion, thirst, hunger, circadian rhythms, and autonomic nervous system control. The episode provides an overview of these functions and sets the stage for future discussions on the brain and nervous system.
