title: Vision in a monkey without striate cortex: a case study creator: Humphrey, Nicholas K subject: Behavioral Neuroscience subject: Neuropsychology subject: Perceptual Cognitive Psychology description: A rhesus monkey, Helen, from whom the striate cortex was almost totally removed, was studied intensively over a period of 8 years. During this time she regained an effective, though limited, degree of visually guided behaviour. The evidence suggests that while Helen suffered a permanent loss of 'focal vision' she retained (initially unexpressed) the capacity for 'ambient vision'. date: 1974 type: Journal (Paginated) type: PeerReviewed format: application/pdf identifier: http://cogprints.org/1757/2/Helen74.pdf identifier: Humphrey, Nicholas K (1974) Vision in a monkey without striate cortex: a case study.
