Neural basis of learning and memory
... Long-term potentiation and long-term depression are enduring (long-lasting) changes in synaptic strength that are brought about by specific patterns of activity at the synapse. These activity-dependent changes are thought to play a critical role in learning and subsequent memory formation. Both have ...
