Identification of the central vestibular projections in man: a positron emission tomography activation study.

abstract：:The reduction in saccade latency when the fixation point is removed (fixation offset effect-FOE) reflects the degree to which fixation neurons are under influence by a stimulus at fixation. Strategic manipulations of oculomotor readiness that bring these neurons under endogenous control reduce the magnitude of the FOE...
