It is well established that environmental enrichment, providing animals with rich sensory, motor, and social stimulation, produces both dramatic increases in the number of synapses in the brain and enhanced learning. However, causal relationships between synapse formation and improved memory have not been definitively established. Now, a new study published by Cell Press in the March 24 issue of the journal Neuron introduces a valuable model system for investigating the role of synapse turnover in learning and memory in adult animals and elucidates mechanisms that link loss of existing synapses and the establishment of new synapses with improved learning...
