運動学習を導くエラー信号の入力源と機能的役割

Abstract

Learning new motor behavior is aided by error signals that occur in association with each attempted behavior. Although sensory error inputs are known to be essential for guiding motor learning, the nature and source of error signals are incompletely understood. Therefore, we applied micro-electrical stimulation in the pretectal nucleus of the optic tract (NOT), which encodes retinal error information during smooth pursuit and sends signals to the cerebellum through the inferior olive. Here we would argue that artificial error information (simulated retinal motion) produced by NOT stimulation could provide instructive signals for visually guided motor learning.
