TMS of the right angular gyrus modulates priming of pop-out in visual search: combined TMS-ERP evidence.

abstract：:The spatial arrangement of preferred directions (PDs) in the primary motor cortex has revealed evidence for columnar organization and short-range order. We investigated the large-scale properties of this arrangement. We recorded neural activity at sites on a grid covering a large region of the arm area of the motor co...
