Residual vision in subjects with damage of the primary visual cortex (striate cortex) has been demonstrated in many previous studies and is taken to reflect the properties of known subcortical and extrastriate visual pathways. In this report we describe psychophysical experiments carried out on a subject clinically blind in half of his visual field (i.e. homonymous hemianopia) caused by striate cortex damage. They reveal the existence of two distinct channels mediating such vision. One channel… 
Spatial and temporal processing in a subject with cortical blindness following occipital surgery
Learning from the pupil: a spatial visual channel in the absence of V1 in monkey and human.
There is a narrowly tuned spatial visual channel that does not require the integrity of V1 in monkey or human, and the pupil holds promise as a non-verbal, indirect method for determining the spatial profile, sensitivity and other properties of residual visual capacity, both in animals and humans.
Spatial channels of visual processing in cortical blindness
It appears that the psychophysical spatial channel‐mediating responses in the absence of any awareness of the visual event have a narrower frequency response than those involved when the patients report some awareness of The method outlined is effective in flagging a 'window of detection' in the spatial frequency spectrum.
Evidence for perceptual learning with repeated stimulation after partial and total cortical blindness
It is shown that perceptual learning can occur through systematic visual field stimulation even in cases of bilateral cortical blindness, and improved visual sensitivity with repeated stimulation is shown.
Residual Vision in a Subject with Damaged Visual Cortex
A subject with perimetrically blind visual areas caused by bilateral brain damage was investigated and an area in the blind visual field was revealed in which the subject perceived a light flash when the experimental black stimulus was presented.
Pupil response as a predictor of blindsight in hemianopia
In a group of 19 subjects with hemi-field cortical blindness, the pupil responses in the majority matched the psychophysical findings for the sensitive spatial frequencies, indicating that it is useful to carry out pupillometry in cortical blind fields as a predictor of intact visual psychophysical function for further rehabilitation procedures.
The role of light scatter in the residual visual sensitivity of patients with complete cerebral hemispherectomy.
It is concluded that the subcortical pathways which survive hemispherectomy cannot mediate voluntary behavioural responses to visual information in the hemianopic field.
Motion specific responses from a blind hemifield.
It is found that GY's early response to fast motion is preserved and correlates with activity elicited in control subjects over area V5, while slow motion, pattern offset, and pattern reversal stimuli failed to elicit responses in GY.
Residual Visual Function in the Absence of the Human Striate Cortex
Remains of visual function in patients who suffer extensive field losses associated with lesions of the striate cortex are discussed, including a patient, GY, who can detect transient light stimuli presented within the ‘blind’ region of his visual field but cannot identify certain colours.


Factors affecting visual sensitivity in a hemianopic subject.
A well-studied subject with visual cortex damage (G.Y.) was tested in his hemianopic field with temporally modulated sinusoidal and square-wave gratings to obtain a detailed spatiotemporal specification of his residual vision and to resolve the discrepancy between negative findings of Hess and Pointer (1989) and previous positive claims.
Residual vision in patients with retrogeniculate lesions of the visual pathways.
Twenty-five subjects have been studied who, as a result of damage to the striate cortex, were 'blind' in extensive areas of the visual fields and the observed dissociation between spatial discrimination of displacement and pattern is examined in relation to the 'two systems' hypothesis of visual function.
Visual capacity in the hemianopic field following a restricted occipital ablation.
Recent animal results suggest strongly that a severe penalty is inflicted when damage to neighbouring posterior cortical areas is added to that of the striate cortex, and human cases in which damage is relatively restricted to area 17, with only minimal damage to surrounding tissue have a renewed interest.
Human visual responses in the absence of the geniculo-calcarine projection.
It is shown that the experimental data cannot be attributed to light scattered from the 'blind' into the normal hemifield, and other mechanisms which may be responsible for the observed responses are examined.
Human saccadic eye movements in the absence of the geniculocalcarine projection.
The results show that blind hemifield stimulation can elicit goal-directed saccades of short latency provided the contrast of the visual stimulus is above the threshold required for saccade generation at the corresponding stimulus eccentricity.
Is blindsight an effect of scattered light, spared cortex, and near-threshold vision?
It is concluded that an adequate case for blindsight has not been made and it is probably impossible to demonstrate the existence of blindsight on purely behavioural grounds.
Spatial and temporal contrast sensitivity in hemianopia. A comparative study of the sighted and blind hemifields.
In comparison with the normal (control) sensitivities obtained in this study, spatial and temporal sensitivities in the sighted hemifield in subjects with striate cortical lesions were both reduced; in addition, the authors were unable to demonstrate greater-than-chance performance at any extrafoveal locations in the blind hem ifield.
Residual Visual Function after Brain Wounds involving the Central Visual Pathways in Man
IT is generally believed that total destruction of visual cortex and optic radiations in man should lead to blindness, and that regional (subtotal) destruction should correspondingly produce

Non-verbal and sensitive methods are available that permit the comparative study of normal and residual visual capacity in human infants, adults and infra-human animals.
