Visual responses in the postarcuate cortex (area 6) of the monkey that are independent of eye position.

abstract：:Recent results on the nature and limits of multisensory enhancement are inconsistent when stimuli are presented across spatial regions. We presented visual, tactile and visuotactile stimuli to participants in two speeded response tasks. Each unisensory stimulus was presented to either the left or right hemispace, and ...
