Essentials: How Your Brain Functions & Interprets the World | Dr. David Berson

In this Huberman Lab Essentials episode, my guest is Dr. David
Berson, PhD, a professor of neuroscience at Brown University and an
expert on the visual system and circadian biology. We explore how
the brain processes visual information, from photons entering the
eye to conscious perception in the cortex. We discuss color vision,
the discovery of melanopsin and intrinsically photosensitive
retinal ganglion cells, and how light regulates our circadian clock
and melatonin release. We also examine the vestibular system's role
in balance and motion detection, the cerebellum's function in motor
coordination, and the midbrain's integration of multiple sensory
inputs. Finally, we discuss the basal ganglia's role in
decision-making and an extraordinary case of neuroplasticity in
visual cortex. Read the episode show notes at hubermanlab.com. More
