Propofol disrupts alpha dynamics in distinct thalamocortical networks underlying sensory and cognitive function during loss of consciousness

Veronica S. Weiner, David W. Zhou, Pegah Kahali, Emily P. Stephen, Robert A. Peterfreund, Linda S. Aglio, Michele D. Szabo, Emad N. Eskandar, Andrés F. Salazar-Gómez, Aaron L. Sampson, Sydney S. Cash, Emery N. Brown, Patrick L. Purdon

The paper shows propofol causes alpha rhythms to shift from posterior to anterior in two distinct thalamocortical networks, disrupting sensory and cognitive function during loss of consciousness.
