Washington: Scientists have discovered 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, according to researchers at Johns Hopkins University."What`s interesting about this protein, AGAP3, is that it is effectively double-sided: One side beefs up synapses in response to brain activity, while the other side helps bring synapse-building back down to the brain`s resting state," said Rick Huganir, from Johns Hopkins University School of Medicine.
