Zap! Magnetic tricks on conscious and unconscious vision.
Blindsight, the remarkable capability to react to unseen visual stimuli, has thus far only been demonstrated in patients and monkeys with a lesion to primary visual cortex. A recent study by Boyer, Harrison and Ro demonstrates blindsight in normal human observers, using TMS to block visual processing. Combined with other work, this opens new vistas towards understanding mechanisms of conscious and unconscious vision.
