A model of memory formation in the pair - association task

Neurons related to pair-association memory have been found in the inferotemporal cortex of monkeys, but their activities do not accord with existing neural network models. We have previously shown that a neural network consisting of excitatory-inhibitory cell pairs is able to explain these neuronal activities; however in order to form the memory, it required an external learning signal. In the present paper, we supplement this model with another network to generate the learning signal. By simply inputting paired patterns in order, this model forms pair-association memories using the interaction between the two networks.
