How the brain replenishes memory molecules



'New research on living neurons has clarified how the brain refreshes the supply of molecules it needs to make new memories. The discovery by scientists at UCSF is reported in the December 22 issue of the journal Neuron and is featured on the journal's cover. Memory formation is thought to involve a strengthening of the communication between neurons in the part of the brain known as the hippocampus. Researchers know that this increased communication results from a surge in the number of receptors on one neuron that is available to bind to the neurotransmitter glutamate released from another neuron. The two neurons meet at a synapse.' More
