The congenital and see-saw nystagmus in the prototypical achiasma of canines: comparison to the human achiasmatic prototype.

abstract：:Two experiments investigated modulatory effects of a surround upon the perceived speed of a moving central region. Both the surround's depth and velocity (relative to the center) were manipulated. The abilities of younger observers (mean age was 23.1 years) were evaluated in Experiment 1, while Experiment 2 was devote...
