WEDNESDAY, June 18 (HealthDay News) "British researchers say they have discovered a means of anticipating how people might behave during a psychotic episode.
The study, by a team at the University of Cambridge, found that patterns of normal brain activity may predispose individuals to different psychosis symptoms.
The researchers compared the brain activity of 15 healthy volunteers before and after they were given ketamine, a psychosis drug that mimics schizophrenia symptoms.
Increased brain activity during some tasks in the normal state predicted behaviors after the participants were given ketamine. For example, those who showed more frontal and temporal brain activity while imaging the sounds of voices in their normal state were more likely to experience strange perceptions after taking ketamine."
