New approaches to visual rehabilitation for cortical blindness: outcomes and putative mechanisms
Cortical blindness is a chronic loss of vision following damage to the primary visual cortex
(V1) or its postchiasmal afferents. Such damage is followed by a brief period of spontaneous …

Rehabilitation of visual perception in cortical blindness
EL Saionz, A Busza, KR Huxlin - Handbook of clinical neurology, 2022 - Elsevier
Blindness is a common sequela after stroke affecting the primary visual cortex, presenting as
a contralesional, homonymous, visual field cut. This can occur unilaterally or, less …

Correction of distortion in flattened representations of the cortical surface allows prediction of V1-V3 functional organization from anatomy
NC Benson, OH Butt, DH Brainard… - PLoS computational …, 2014 - journals.plos.org
Several domains of neuroscience offer map-like models that link location on the cortical
surface to properties of sensory representation. Within cortical visual areas V1, V2, and V3 …

Spared perilesional V1 activity underlies training-induced recovery of luminance detection sensitivity in cortically-blind patients
Damage to the primary visual cortex (V1) causes homonymous visual-field loss long

A detection theoretic explanation of blindsight suggests a link between conscious perception and metacognition
Blindsight refers to the rare ability of V1-damaged patients to perform visual tasks such as
forced-choice discrimination, even though these patients claim not to consciously see the …

The nature of consciousness in the visually deprived brain
Vision plays a central role in how we represent and interact with the world around us. The
primacy of vision is structurally imbedded in cortical organization as about one-third of the …

Fast and reversible neural inactivation in macaque cortex by optogenetic stimulation of GABAergic neurons
Optogenetic techniques for neural inactivation are valuable for linking neural activity to
behavior but they have serious limitations in macaques. To achieve powerful and temporally …

The primary visual cortex, and feedback to it, are not necessary for conscious vision
DH Ffytche, S Zeki - Brain, 2011 - academic.oup.com
A compelling single case report of visual awareness (visual qualia) without primary visual
cortex would be sufficient to refute the hypothesis that the primary visual cortex and the back …
