Massachusetts General Hospital and Massachusetts Institute of Technology (MIT) Study Discovers How Brain Activity Changes When Anesthesia Induces Unconsciousness

Investigators at Massachusetts General Hospital (MGH) and Massachusetts Institute of Technology (MIT) have identified for the first time a pattern of brain activity that appears to signal exactly when patients lose consciousness under general anesthesia. Although their study only involved use of one anesthetic drug, propofol, the researchers believe that their findings will apply to other forms of general anesthesia and could lead to better ways of monitoring anesthetized patients.
