Mouse brain cells activated, reactivated in learning and memory

Mouse brain cells activated, reactivated in learning and memory.

Neuroscientists have for the first time shown individual mouse brain cells being switched on during learning and later reactivated during memory recall.

“The exciting part is that we are now in a position to answer a fundamental question about memory,” Wiltgen said. “It’s been assumed for a long time that the hippocampus is essential for memory because it drives reactivation of neurons (nerve cells) in the cortex. The reason you can remember an event from your life is because the hippocampus is able to recreate the pattern of cortical activity that was there at the time.”
