| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Ocular following response (OFR) is a slow tracking eye movement at ultra-short latency. It is elicited by sudden drifting movements of a large-field visual stimulus in primates, helps to stabilize the eyes on the visual scene. The previous behavioral study suggested that the OFRs of the monkey are subject to extensive visually mediated adaptive regulation. Previous single unit recordings and chemical lesion studies have reported that the OFR is mediated by a pathway that includes the medial superior temporal (MST) area of the cortex and the ventral paraflocculus of the cerebellum. There is much evidence to suggest that the cerebellum is the critical site for motor learning. In the present study, to understand how the MST contributes to the adaptation of the OFRs, we recorded single unit activities from the MST area in the step-down sequences. In the first 50 trials, the step-down sequences immediately produced decreases in ocular following responses, but no changes in neuronal activities of the most MST neurons. | |
