| Abstract(in English) | It has been shown that environmental information is represented as population codes in cortical sensory areas. How does the brain utilize these population codes? In this paper, we examine this problem using the smooth pursuit eye movements(pursuit). During pursuit, velocity and acceleration of a visual target are represented as population codes in the higher cortical visual areas, MT and MST, while motor commands for the eye movements are represented as firing rate codes in the Purkinje cells of cerebellum. We propose that the acquisition of transformation of these neural representations is achevied through synaptic plasticity in the cerebellar cortex, and construct the model based on the feedback-error-learning. Without any mathmatical methods such as maximum likelihood estimate, our scheme successfully demonstrates the neural code change by means of well-known cerebellar curcuit and the learning rule based on physiological experiments. |
