Probabilistic Synaptic Transmission in the Associative Net

摘要

The associative net model of heteroassociative memory with binary-cal- usd synapses has been extended to include recent experimental data in- dicating that in the hippocampus, one form of synaptic modification is a change in the probability of synaptic transmission. Pattern pairs as stored in the net by a version of the Hebbian learning rule that changes the probability of transmission at synapses where the presynatic and post- synaptic units are simultaneously active from a low, base value to a high, modified value.
