Effect of stimulus localisation on motion-onset VEP

Abstrakt

Reliable motion-onset visual evoked potentials (result of the dorsal stream activation) were recorded to motion stimuli with the temporal frequency of five cycles per seconds in 20 different locations with eccentricity up to 42° to periphery of the visual field. Observed retinotopic dependence showed that the motion response includes position information and that the motion-onset VEPs are not generated solely in the higher extrastriate areas (MT or MST).
