2P1-G08 Self-organization of somatosensory area through STDP with interaction between a body and an environment

Abstract

Kohonen's self Organizing Map (SOM) is one of the candidates for construction of somatosensory area which have a topological map corresponding own body. Information representation in SOM is continuous value as rate coding although neurons deliver information by spiking. Recently, Spike timing dependent plasticity (STOP) learning rule is proposed from researches of brain physiology. In this paper, for preliminary experiment, we have examined whether a somatosensory map for simple musculoskeletal system is constructed by spindle output through STOP. In the result, we confirmed that selective neurons for each input emerged, where topological map is not constructed.
