Research deciphers 'déjà-vu' brain mechanics

Research deciphers 'déjà-vu' brain mechanics - MIT News Office
"Tonegawa, a Howard Hughes Medical Institute investigator and a frequent world traveler, described his own occasional experience of finding the airport in a new city uncannily familiar. This occurs, he said, because of the similarity of the modules--gates, chairs, ticket counters--that comprise airports worldwide. It is only by seeking out unique cues that the specific airport can be identified, he said. "In this study, we have revealed that learning in the dentate gyrus is crucial in rapidly recognizing and amplifying the small differences that make each place unique," Tonegawa said."
