| Abstract(in English) | We study a neural network model for inferior temporal cortex proposed by Amit et al. in the finite memory loading and sparase coding. We show that uncorrelated Hopfield type and some correlated attractors coexist, and examine the retrieval processes for these attractors when the initial state is set to a noisy-degraded stored pattern. We found that there exists a critical value of initial overlap, that is, the system converges to the correlated attractor when the degree of noise is large, otherwise to the Hopfield type attractor. We resolve controversy of previously obtained experimental findings regarding neuron properties in the inferior temporal cortex, and propose a novel experimental paradigm based on these theoretical results. |
