Emery Brown, Professor of Brain and Cognitive Sciences at MIT and Professor of Anesthesia at Harvard, describes how general anesthesia induced by drugs such as Propofol alters neural oscillations in the brain, as measured with EEG. He presents a model of the neural circuitry underlying the impact of anesthesia on neural signals, and shows how these changes vary with age. Understanding this process may lead to clinical methods for actively restoring brain function after anesthesia that may speed recovery and reduce cognitive dysfunction.
