Hemispace Matters in Normal Individuals: Effects of Gaze and Hand Location on Corticospinal Excitability

Effects of hemispace on perception and action are commonly observed in stroke survivors. In the hemispatial neglect syndrome, for example, patients fail to reliably perceive, orient to or initiate action towards stimuli in contralesional space. Stimulus location may also affect higher-level cognitive processes like language, however. Effects of hemispace on perception and action have not been extensively explored in normal individuals. Using single-pulse transcranial magnetic stimulation (TMS) over primary motor cortex, the present study examined hemispace effects on motor evoked potentials (MEPs).
