This is the first episode of Huberman Lab Essentials — short episodes (approximately 30 minutes) focused on essential science and protocol takeaways from past Huberman Lab episodes. This Essentials episode introduces how the nervous system creates sensations, perceptions, emotions, thoughts, and behaviors, as well as how we can change our nervous system — a phenomenon known as neuroplasticity. Essentials will be released every Thursday, and our full-length episodes will still be released every Monday. Access the show notes for this episode at hubermanlab.com.
