How the brain maintains an accurate and stable representation of visual target locations despite the occurrence of saccadic gaze shifts is a classical problem in oculomotor research. Here we test and dissociate the predictions of different conceptual models for head-unrestrained gaze-localization behavior of macaque monkeys. We adopted the double-step paradigm with rapid eye-head gaze shifts to...

In an experimental double-blind placebo study of 18 subjects (mean age 26.2 years), we investigated the effect of three blood alcohol concentrations (0.0%, 0.05% and 0.1%) on five visuomotor reading parameters: (1) number of eye fixations per 100 words read; (2) the number of words read per minute; (3) the number of regressions per 100 words read; (4) the saccadic length; (5) the duration of ey...

Visual and motor coordinate systems have different computational advantages for motor sequence. This paper proposes that the multiple loops that link the basal ganglia (BG) and frontal cortical areas take their different advantages and specialize in acquisition and execution of visuomotor sequence. The central idea of the model is that a visuomotor sequence is easier to learn by visual coordina...
