UCLA psychologists have used brain-imaging techniques to study what happens to the human brain when it slips into unconsciousness. Their research, published Oct. 17 in the online journal PLOS Computational Biology, is an initial step toward developing a scientific definition of consciousness.

“In terms of brain function, the difference between being conscious and unconscious is a bit like the difference between driving from Los Angeles to New York in a straight line versus having to cover the same route hopping on and off several buses that force you to take a ‘zig-zag’ route and stop in several places,” said lead study author Martin Monti, an assistant professor of psychology and neurosurgery at UCLA.

UCLA psychologists have taken a significant step toward answering these questions, identifying for the first time the brain regions associated with the successful spread of ideas, often called “buzz.”

Study of seventh and eighth graders finds no difference between boys, girls

Bullying, whether it’s physical aggression or spreading rumors, boosts the social status and popularity of middle school students, according to a new UCLA psychology study that has implications for programs aimed at combatting school bullying. In addition, students already considered popular engage in these forms of bullying, the researchers found.

The psychologists studied 1,895 ethnically diverse students from 99 classes at 11 Los Angeles middle schools. They conducted surveys at three points: during the spring of seventh grade, the fall of eighth grade and the spring of eighth grade. Each time, students were asked to name the students who were considered the “coolest,” the students who “start fights or push other kids around” and the ones who “spread nasty rumors about other kids.” (more…)
