Abstract

Three groups of subjects, normal controls, right brain damaged patients with and without heminattention, were required to bisect a line in presence of a fixed or a moving background.

The stimulus moving horizontally toward the left or the right induced an optokinetic nystagmus with a slow phase coherent with the direction of the movement: together with the optokinetic nystagmus, a displacement of the subjective midpoint, as compared to the condition with a fixed background, was observed in all three groups of subjects.
