Abstract

Neurons in area VI are responsible for visual processing of the local properties of visual array while the lager receptive fields of extra-striate visual areas such as V4 and V.5 serve to process global representations. In adults, transitions in global coherence of both form and motion yield reliable visual event-related potentials (VERPs) with scalp distributions that are topographically distinct. Ten adult students at UCL participated in the current VERP study, which compared steady-state stimuli, which have rapid transitions between coherent and incoherent states, to transient stimuli, which have longer intervals between transitions, for both form and motion. Analysis of VERP responses determined that the overall topography is the same for both states implying that the two modes of stimulation activate the same cortical areas. This discovery will be helpful in future fMRI studies examining extrastriate global processing.
