Consecutive face recognition by association cortex-entorhinal cortex-hippocampal formation modal

In this paper, we propose a neural network model which incorporates neurophysiological knowledge into Jones´s hypothesis, i.e., the association cortex - entorhinal cortex - hippocampal formation model (AEH model). In this model, the inhibitory action from the inferotemporal cortex to parietal cortex has a gating role for activation of the reverberatory closed circuit between the entorhinal cortex and hippocampal formation. The successive recognition performance of the AEH model was tested using human face images. In the experiments, face images were presented to the AEH model twice. Twenty human faces were tested to learn and recollect successively either in a series or in a block. In both tests, the recognition performance of the AEH model was nearly 100 percent. In the memory consolidation experiments, when face images were presented five times in series, potentiation of long-term memory occurred without any distortions.
