متن کاملEfference copy failure during smooth pursuit eye movements in schizophrenia.
Abnormal smooth pursuit eye movements in patients with schizophrenia are often considered a consequence of impaired motion perception. Here we used a novel motion prediction task to assess the effects of abnormal pursuit on perception in human patients. Schizophrenia patients (n = 15) and healthy controls (n = 16) judged whether a briefly presented moving target ("ball") would hit/miss a statio...
متن کاملSmooth pursuit eye movements and schizophrenia: literature review.
OBJECTIVE To review the scientific literature about the relationship between impairment on smooth pursuit eye movements and schizophrenia. METHODS Narrative review that includes historical articles, reports about basic and clinical investigation, systematic reviews, and meta-analysis on the topic. RESULTS Up to 80% of schizophrenic patients have impairment of smooth pursuit eye movements. D...
متن کاملSmooth pursuit eye movements to isoluminant targets.
At slow speeds, chromatic isoluminant stimuli are perceived to move much slower than comparable luminance stimuli. We investigated whether smooth pursuit eye movements to isoluminant stimuli show an analogous slowing. Beside pursuit speed and latency, we studied speed judgments to the same stimuli during fixation and pursuit. Stimuli were either large sine wave gratings or small Gaussians blobs...
متن کاملManual tracking enhances smooth pursuit eye movements.
Previous studies have reported that concurrent manual tracking enhances smooth pursuit eye movements only when tracking a self-driven or a predictable moving target. Here, we used a control-theoretic approach to examine whether concurrent manual tracking enhances smooth pursuit of an unpredictable moving target. In the eye-hand tracking condition, participants used their eyes to track a Gaussia...
