| Abstract(in English) | In this study, eye movements of twenty-five human subjects were recorded by eye tracking system, and their brain activities measured by functional magnetic resonance imaging (fMRI) when they were tracking a small target of laser spot moving sinusoidally with or without blinking. The phase of their eye velocities was not delayed very much to the one on target velocity regardless whether target was blinked or not. This confirms that the eye movements recorded in our study were controlled predictively. The activities when target was blinked was increased in the monkey FEF and MST homologue than not blinked, and decreased in the occipital pole. These results sugget that the activities specifically increased during the target blink task is closely-linked to the information for the predictive tracking, while the activities dcreased are correlated with visual inputs. |
