... or learning. Learning and memory are thought to occur through LTP. This is a system in which synapses become increasingly sensitive so that a steady level of pre-synaptic stimulation becomes converted into a larger post-synaptic output.

...ng-term potentiation (LTP), a physiological change thought to be important for learning and memory, also was enhanced in the NR2B mice.
