How Your Brain Works & Changes

Today’s episode provides an introduction to how the nervous system works to create sensations, perceptions, emotions, thoughts and behaviors, as well as how we can change our nervous system—a phenomenon known as neuroplasticity. The information sets the stage for all Huberman Lab podcast episodes that follow by covering neurons, synapses, brain chemicals and the rhythms that control our ability to focus, learn and sleep… and more.
