Summary: Researchers shed new light on the molecular and genetic basis of long-term memory formation in the brain. A new study reveals a single stimulation to the synapses of hippocampal neurons triggered numerous cycles where the memory-coding Arc gene produced mRNA molecules that were then translated into synapse-strengthening Arc proteins. From the findings, researchers determined a novel feedback loop that helps explain how short-lived mRNA and proteins create long-term memories in the brain.
