New York: Know what happens inside people's brains when they watch movies together in a theatre? Their brain activity gets synchronised as they watch intense scenes.
Structured movies that use a lot of cinematic devices and carefully composed shots do the synchronising effect to the brain in a better way than movies of unstructured reality, researchers say.
Uri Hasson, a psychologist at Princeton University analysed brain scan data his team collected as people watched several different video clips.
When people watched tense scenes, there was a significant correlation in activity across nearly 70 percent of their cortex.
"The movie takes over the brain responses of the viewers," Hasson was quoted as saying.
He showed his findings to a team of renowned filmmakers at an event recently hosted by the Academy of Motion Picture Arts and Sciences.
"If people's brains were out of sync during a movie, that might be a sign that their minds were wandering," Hasson said.
According to him, filmmakers in the future can use brain scans to gauge how viewers' brains respond to different aspects of a movie, wired.com reported.
