Research Abstract

In the present study, to explore the neuronal mechanism during motor learning, we recorded single unit activities from the medial superior temporal area (MST) of the cortex in awake behaving monkeys. Motor learning was induced by applying an adapting paradigm to monkeys repeatedly (step-down sequences). In the early phase of motor learning in OFR, step-down sequences immediately produced decreases in OFRs, but produced no changes in neuronal activities of MST neurons. The firing patterns in most MST neurons were well reconstructed using retinal error components, suggesting that MST firings encode sensory information while motor learning. These results indicate that motor learning in OFR occur downstream from MST, possibly within the cerebellum.
