Electrocorticography Links Human Temporoparietal Junction to Visual Perception

Electrical stimulation of visual cortex can produce a visual percept (phosphene). We electrically stimulated visual cortex in human patients implanted with subdural electrodes while recording from other brain sites. Across experimental manipulations, we found that phosphene perception occurred only...

description Electrical stimulation of visual cortex can produce a visual percept (phosphene). We electrically stimulated visual cortex in human patients implanted with subdural electrodes while recording from other brain sites. Across experimental manipulations, we found that phosphene perception occurred only if stimulation evoked high-frequency gamma oscillations in the temporoparietal junction (TPJ), a brain region associated with visual extinction and neglect. Electrical stimulation of TPJ modified detectability of low-contrast visual stimuli.
