A new understanding of how anesthesia and anesthesia-like states are controlled in the brain opens the door to possible new future treatments of various states of loss of consciousness, such as reversible coma, according to Hebrew University of Jerusalem scientists.

In an article published in the Journal of Neuroscience, the scientists, Marshall Devor, the Cecile and Seymour Alpert Professor of Pain Research, graduate student Ruth Abulafia and research associate Dr. Vladimir Zalkind describe their discovery of an area of the brain that participates in the control of "alert status."

Loss of response to painful stimuli and loss of consciousness are the most striking characteristics of surgical anesthesia and anesthesia-like states, such as concussion, reversible coma, and syncope (fainting). These states also exhibit behavioral suppression, loss of muscle tone, a shift to the sleep-like "delta-wave" EEG pattern, and depressed brain metabolism.
