Anesthesia Induces Unconsciousness by Destabilizing Brain Activity

Neuroscientists have discovered that the anesthesia drug propofol causes unconsciousness by disrupting the brain's balance between stability and excitability. The drug leads to increasingly unstable brain activity, preventing the brain from maintaining normal consciousness.

Predisposition to Accidental Awareness Under Anesthesia Identified

As many as one in four patients who receive anesthesia may suffer accidental awareness during their procedure. Researchers have identified specific brain structures that may predict whether a person will experience accidental awareness under anesthesia. The findings will help identify patients who require higher than average doses of anesthesia.

Anesthesia Doesn’t Simply Turn Off the Brain, It Changes Its Rhythms

Propofol, the commonly used anesthetic, alters and controls the dynamics of the brain's rhythms. The findings can help doctors better monitor patients under anesthesia with the aid of EEG.
