Neuroscientists discover a brain circuit dedicated to retrieving memories
MIT neuroscientists have proven, for the primary time, that recalling a reminiscence requires a “detour” circuit that branches off from the unique reminiscence circuit. This low-magnification picture reveals that hippocampal CA1 neurons (pink) and dorsal subiculum neurons (inexperienced) might be genetically recognized utilizing two completely different protein markers. Credit score: Dheeraj Roy/Tonegawa Lab, MIT When we now have a brand new expertise, the reminiscence of that occasion is saved in a neural circuit that connects a number of components of the hippocampus and different mind buildings. Every cluster of neurons could retailer completely different features of the reminiscence, corresponding to the situation the place the occasion occurred or the feelings related to it. Neuroscientists who research reminiscence have lengthy believed that once we recall these reminiscences, our brains activate the identical hippocampal circuit that was activated when t...
