Huberman Lab

In this Huberman Lab Essentials episode, my guest is Dr. Eddie Chang, MD, a neurosurgeon and Chair of the Department of Neurological Surgery at the University of California, San Francisco (UCSF). We discuss the neural circuits underlying speech and language, including how the brain controls the larynx, vocal folds and articulators to shape breath into words. We also explore his pioneering work on speech neural prosthetics — brain-machine interfaces that allow paralyzed patients to communicate by decoding neural activity into speech and avatar-driven facial expressions. Additionally, we examine the neurobiology of stuttering, the role of auditory feedback in fluent speech, and the broader ethical questions surrounding brain augmentation technologies.

Dr. Nick Epley, PhD, is a professor of behavioral science at the University of Chicago and a leading expert on the science of social connection. We discuss how seemingly small daily interactions with strangers (as well as with people we know) can meaningfully improve our mental and physical health. Dr. Epley also explains how to reduce social anxiety using simple and easily accessible science-supported tools. We also discuss the data on assumptions — both the ones we and others make — and why so often those are wrong when it comes to social dynamics. Read the episode show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, I explain the neural circuits that activate and control aggressive states and behaviors. I discuss how hormones, genes and environmental factors such as day length can shift our aggressive tendencies. I also share science-based tools for modulating aggression, including sunlight exposure, heat therapy and supplementation with ashwagandha or acetyl-L-carnitine.

Dr. Kentaro Fujita, PhD, is a professor of psychology at The Ohio State University and an expert in the science of self-control and motivation. We discuss the best tools for developing strong self-control: to do more of what you aspire to and cease doing things you would like to avoid. We discuss why you need more than one form of willpower to achieve sustained motivation and overcome procrastination. Dr. Fujita also clarifies the data on the 2-marshmallow test, delayed gratification and intrinsic vs. extrinsic motivation. Read the show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, my guest is Dr. Casey Halpern, MD, a professor of neurosurgery at the Perelman School of Medicine at the University of Pennsylvania. We discuss how deep brain stimulation and other neuromodulation approaches are being used to treat Parkinson's disease, obsessive-compulsive disorder (OCD), binge eating disorder and depression-related symptoms. We also explore the brain circuits that drive compulsions, cravings and impulsivity, as well as emerging non-invasive tools for predicting and treating harmful behaviors.
