The posterior parietal cortex contributes to visuomotor processing for saccades in blindsight macaques

The posterior parietal cortex contributes to visuomotor processing for saccades in blindsight macaques

Rikako Kato et al. use PET imaging to examine altered brain activity in blindsight macaques that lack visual awareness yet can still perform visuomotor tasks. They report that blindsight macaques exhibit a significant change in activity of the lateral bank of the intraparietal sulcus (lbIPS) bilater...
