Spatiotemporal Analysis of Visuospatial Attention and Modulation by Repetitive Transcranial Magnetic Stimulation (rTMS)

Introduction: Previous studies showed that repetitive TMS produces temporary virtual lesions. If performed over the right posterior parietal cortex (PPC) visuospatial tasks are impaired due to the effect of the stimulation [1]. The aim of the present study was to deconvolute the temporal dynamics of the neural processes involved in line bisection judgement tasks and their dependency on the function of the PPC. Materials and Methods: We studied twelve right-handed healthy subjects. The performance on a computerized visuo-spatial line-bisection judgement task was examined before and after the application of rTMS o…
