Mechanism of Cell Assembly Formation in Learning of Hand Regard

Abstract

It is known that inhibitory connections play an important role in the formation of cell assemblies that retain memory traces. In a previous study simulating hand regard behavior, the cell assembly was self-organized. However, it was not clear what kind of mechanism formed inhibitory connections. In this paper, we investigated the relationship between hand movement and weight changes in order to elucidate the mechanism by which inhibitory connections are formed. As a result, it was found that the repetition of the reciprocating movement across the field of view, which is performed in the learning process of hand regard, leads to the reduction of the weights, resulting in inhibitory connections.
