Research Abstract |
Following two experiments were conducted in this study : (1) The effects of stimulus size and location on the mouse optokinetic response (OKR) were examined. Presenting 5 degrees-width stimuli at different vertical locations revealed the spatial distribution of optokinetic sensitivity across the retina. The most sensitive part of the visual field was located at +25 degrees. (2) Roll-tilt perception and ocular counter-rolling (OCR) under whole body roll-tilt (condition A) and interaural centrifugal acceleration (condition B) were examined on humans. Properties of roll-tilt perception and OCR were largely different between two conditions. These data will support our next experiment on the mechanisms of dynamic visual acuity in pursuing a high-speed moving object.
