| Abstract: | A number of memory models have been proposed. These all have the basic structurethat excitatory neurons are reciprocally connected by recurrent connections togetherwith the connections with inhibitory neurons, which yields associative memory (i.e.,pattern completion) and successive retrieval of memory. In most of the models, asimple mathematical model for a neuron in the form of a discrete map is adopted.It has not, however, been clarified whether behaviors like associative memory andsuccessive retrieval of memory appear when a biologically plausible neuron modelis used. In this paper, we propose a network model for associative memory andsuccessive retrieval of memory based on Pinsky-Rinzel neurons. The state of patterncompletion in associative memory can be observed with an appropriate balanceof excitatory and inhibitory connection strengths. Increasing of the connectionstrength of inhibitory interneurons changes the state of memory retrieval from associativememory to successive retrieval of memory. We investigate this transition. |
