Experimental design. Subject head model fixating on a stimulus screen placed 90 cm away. The visual stimulus is an angularly sweeping black and white reversing radial grid (10 Hz reversal) on a 50% gray background. The wedge extends over a polar angle of 60° and a radial angle of 2.5° – 10.5° and was rotated in steps of 10° each second.
