Modeling Synaptic Plasticity
... Synapses are the structures through which neurons communicate, and the loci of information storage in neural circuits. Synapses store information (‘learn’) thanks to synaptic plasticity: the efficacy of the communication between the two neurons connected by the synapse can change, as a function of t ...
