Differential extrageniculostriate and amygdala responses to presentation of emotional faces in a cortically blind field. by Morris, J, DeGelder, B, Weiskrantz, L, Dolan, R

Increased sensitivity after repeated stimulation of residual spatial channels in blindsight. by Sahraie, A, Trevethan, C, MacLeod, M, Murray, A, Olson, J, Weiskrantz, L

“…Lesions of the occipital cortex result in areas of cortical blindness affecting the corresponding regions of the patient's visual field. …”

Unseen facial and bodily expressions trigger fast emotional reactions. by Tamietto, M, Castelli, L, Vighetti, S, Perozzo, P, Geminiani, G, Weiskrantz, L, de Gelder, B

“…Emotional contagion reactions to different classes of consciously seen and "unseen" stimuli were compared by presenting pictures of facial or bodily expressions either to the intact or blind visual field of two patients with unilateral destruction of the visual cortex and ensuing phenomenal blindness. …”

Early extrastriate activity without primary visual cortex in humans. by Rossion, B, de Gelder, B, Pourtois, G, Guérit, J, Weiskrantz, L

“…A P1 response was also observed with stimulation of the blind field, although slightly delayed (20 ms) and reduced. …”

Intact navigation skills after bilateral loss of striate cortex. by de Gelder, B, Tamietto, M, van Boxtel, G, Goebel, R, Sahraie, A, van den Stock, J, Stienen, B, Weiskrantz, L, Pegna, A

“…Patient TN suffered two strokes in succession, lesioning each visual cortex in turn and causing clinical blindness over his whole visual field. Functional and anatomical brain imaging assessments showed that TN completely lacks any functional visual cortex. …”

Color contrast processing in human striate cortex. by Kentridge, R, Heywood, C, Weiskrantz, L

“…When presented with such displays, both normal observers and those with cerebral achromatopsia (cortical color blindness) judge the color appearance of such stimuli on the basis of the chromatic contrast the stimuli make against their background rather than on the physical wavelengths of the light emitted from them. …”

Trying to bridge some neuropsychological gaps between monkey and man. by Weiskrantz, L

“…In other instances, they may derive from inadequate or inappropriate methods of testing human subjects, and attention is focused on two major examples: memory disorders associated with medial temporal lobe lesions and blindness associated with occipital lesions in man. …”

Collicular vision guides nonconscious behavior. by Tamietto, M, Cauda, F, Corazzini, L, Savazzi, S, Marzi, C, Goebel, R, Weiskrantz, L, de Gelder, B

“…Following destruction or deafferentation of primary visual cortex (area V1, striate cortex), clinical blindness ensues, but residual visual functions may, nevertheless, persist without perceptual consciousness (a condition termed blindsight). …”

Parameters affecting conscious versus unconscious visual discrimination with damage to the visual cortex (V1). by Weiskrantz, L, Barbur, J, Sahraie, A

“…When the visual (striate) cortex (V1) is damaged in human subjects, cortical blindness results in the contralateral visual half field. …”

The Ferrier lecture, 1989. Outlooks for blindsight: explicit methodologies for implicit processes. by Weiskrantz, L

“…When this route is damaged in man, apparent blindness in a corresponding part of the visual field occurs, despite the integrity of the other parallel pathways. …”

Unseen stimuli modulate conscious visual experience: evidence from inter-hemispheric summation. by de Gelder, B, Pourtois, G, van Raamsdonk, M, Vroomen, J, Weiskrantz, L

“…Redundant stimulation in the blind field led to shorter latencies for stimulus detection in the intact field. …”

Form discrimination in a case of blindsight. by Trevethan, C, Sahraie, A, Weiskrantz, L

“…We have demonstrated that DB could successfully identify outline low contrast images of objects, make successful 'same/different' discriminations for pairs of stimuli presented in his blind field and identify complex images (digital photographs) presented entirely within his cortically blind field. …”

Can blindsight be superior to 'sighted-sight'? by Trevethan, C, Sahraie, A, Weiskrantz, L

“…Blind field performance was compared to his sighted field performance and to an age-matched control group (n=6). …”
