Visual capacity in the hemianopic field following a restricted occipital ablation.
TLDR
DAMAGE to striate cortex and neighbouring regions in man is well known to produce severe loss of visual capacity in correlated legions of the visual field (Holmes, 1918). Expand

Increased sensitivity after repeated stimulation of residual spatial channels in blindsight
Lesions of the occipital cortex result in areas of cortical blindness affecting the corresponding regions of the patient's visual field. The traditional view is that, aside from some spontaneousExpand

Differential extrageniculostriate and amygdala responses to presentation of emotional faces in a cortically blind field.
Patient G.Y. is able to discriminate emotional facial expressions presented in his blind (right) hemifield despite an extensive lesion of the corresponding (left) striate cortex. One proposal is thatExpand

Subcortical Connections to Human Amygdala and Changes following Destruction of the Visual Cortex
Nonconscious [1-6], rapid [7, 8], or coarse [9] visual processing of emotional stimuli induces functional activity in a subcortical pathway to the amygdala involving the superior colliculus andExpand
