title: Repetitive TMS over V5/MT shortens the duration of spatially localized motion aftereffect: the effects of pulse intensity and stimulation hemisphere.
abstract: Causal relevance of the cortical area V5/MT for motion (aftereffect) perception has been shown when rTMS pulses have been applied onto this area, leading to disruption of the percept. Typically, the inducing and test stimuli have consisted in a spatially contiguous area from where stimulation is presented. Observers have had no need to divide attention between spatially remote areas including motion-related signals with different vectors. Here we present experimental results showing that an adverse effect of rTMS on motion aftereffect can be obtained when contralateral V5/MT is stimulated and subjects have to report which one of the two simultaneous aftereffect percepts separated into two hemifields decays before the other. The effect appears stronger following right hemisphere V5/MT stimulation and is clearly evident even with weak rTMS pulses.
