Newly Discovered ‘Switch’ Plays Dual Role in Memory Formation

Pin It

Researchers at Johns Hopkins have uncovered a protein switch that can either increase or decrease memory-building activity in brain cells, depending on the signals it detects. Its dual role means the protein is key to understanding the complex network of signals that shapes our brain’s circuitry, the researchers say.

….Although it might seem the two different functions are behaving at cross-purposes, Oku says, it also could be that nature’s bundling of these functions together in a single protein is an elegant way of enabling learning and memory while preventing dangerous overstimulation.
