Data from: Fractionation of parietal function in bistable perception probed with concurrent TMS-EEG

When visual input has conflicting interpretations, conscious perception
can alternate spontaneously between these possible interpretations. This
is called bistable perception. Previous neuroimaging studies have
indicated the involvement of two right parietal areas in resolving
perceptual ambiguity (ant-SPLr and post-SPLr). Transcranial magnetic
stimulation (TMS) studies that selectively interfered with the normal
function of these regions suggest that they play opposing roles in this
type of perceptual switch. In the present study, we investigated this
fractionation of parietal function by use of combined TMS with
electroencephalography (EEG). Specifically, while participants viewed
either a bistable stimulus, a replay stimulus, or resting-state fixation,
we applied single pulse TMS to either location independently while
simultaneously recording EEG. Combined with participant’s individual
structural magnetic resonance imaging (MRI) scans, this dataset allows for
complex analyses of the effect of TMS on neural time series data, which
may further elucidate the causal role of the parietal cortex in ambiguous
perception.
