Contralateral visual search deficits following TMS.
Transcranial magnetic stimulation of posterior parietal vs. superior temporal sites cause differential effects on conventional conjunction vs. feature search tasks, respectively. We now report that when a decision has to be made on the target's left/right location, different lateralized deficits emerge in these two cases. With full-field arrays, we found a specific PPC search deficit for contralateral space. With smaller, structured arrays presented in left or right hemispace, we found a specific STG deficit for contralateral parts of the array.
