My research program aims to help understand the cellular and neurochemical mechanisms regulating states of consciousness and state-dependent changes in physiology.
The goals of Lydic's research are elucidating the mechanisms by which sleep, opioids, and volatile anesthetics modulate pain and depress breathing and arousal. The evolutionary perspective and current data support the view that neurons generating sleep and wakefulness preferentially modulate the ability of opioids, hypnotics, and anesthetics to alter pain, behavioral affect, and states of waking consciousness.
