Keynote Spotlight Professor William Wisden (UK) Neurocircuitry of Sleep
Dr. Wisden’s research has helped advance our understanding of the neural systems that regulate sleep and wakefulness. His work has contributed to major discoveries regarding how sleep is controlled within the brain and how sleep-related circuits influence health, cognition, and behavior.
As neuroscience continues to reveal new insights into sleep regulation, understanding these biological mechanisms remains essential for both researchers and clinicians.
Attendees in Montreal will have the opportunity to hear directly from one of the field’s leading experts as he explores current discoveries and future directions in sleep neurobiology.
