“…49,51 These include standard neuropsychological instruments such as the Warrington Recognition Memory test, 52 and the Benton Face Recognition test, 53 as well as our own experimental tests of discrimination of famous from anonymous faces, 54 and of facial imagery. 55 (In addition, the averaged upright configuration perception data from this report were also presented in one of these prior studies. 49 ) Cluster analysis confirmed at least two groups of subjects with SDD: one with normal face recognition (SDD-1) and one with abnormal face recognition (SDD-2).…”

“…In contrast, the associative subtype of prosopagnosia (i.e., a deficit in recognizing various associations between facial identity and related attributes such as certain types of semantic information) is generally considered to be attributable to damages overriding the anterior temporal cortical areas (Damasio et al, 1982;De Renzi et al, 1991;Barton et al, 2002;Barton and Cherkasova, 2003). The APA task to which we subjected the monkeys in the present study was designed to functionally simulate semantic associations with facial identities, as such associations are apparently broken in patients with the associative subtype of prosopagnosia.…”

“…In the narrow sense, prosopagnosia indicates a cognitive inability to identify familiar individuals by their faces. Previous literature has suggested that there are two basic types of prosopagnosia (Damasio et al, 1982;De Renzi et al, 1991;Barton et al, 2002;Barton and Cherkasova, 2003). One of these two subtypes is apperceptive prosopagnosia, which implies a deficit in face recognition itself.…”

To investigate the neural basis of the associative aspects of facial identification, we recorded neuronal activity from the ventral, anterior inferior temporal cortex (AITv) of macaque monkeys during the performance of an asymmetrical paired-association (APA) task that required associative pairing between an abstract pattern and five different facial views of a single person. In the APA task, after one element of a pair (either an abstract pattern or a face) was presented as a sample cue, the reward-seeking monkey correctly identified the other element of the pair among various repeatedly presented test stimuli (faces or patterns) that were temporally separated by interstimulus delays. The results revealed that a substantial number of AITv neurons responded both to faces and abstract patterns, and the majority of these neurons responded selectively to a particular associative pair. It was demonstrated that in addition to the view-invariant identity of faces used in the APA task, the population of AITv neurons was also able to represent the associative pairing between faces and abstract patterns, which was acquired by training in the APA task. It also appeared that the effect of associative pairing was not so strong that the abstract pattern could be treated in a manner similar to a series of faces belonging to a unique identity. Together, these findings indicate that the AITv plays a crucial role in both facial identification and semantic associations with facial identities.

“…Stroke patients are known to be left with prosopagnosia as residual deficit and specific localised lesions of these areas had been identified with this problem. 32,33 Balint's syndrome, a triad of simultagnosia, ocular apraxia and optic ataxia is described as a result of trauma, embolic stroke or even sub-acute HIV encephalitis. 34 Palinopsia (Perseveration of visual image even after the causative object is removed from the visual field otherwise described as 'persisting after-images') can result from right occipital damage due to stroke, trauma or tuberculoma.…”

Visual loss is a common presenting symptom in the Outpatient Departments of Neurology, Ophthalmology and General Medicine disciplines. The present prospective study aims at evaluating 48 patients with partial or total visual loss as the predominant or only presenting symptom and with no associated ocular problems like cataract, glaucoma or diabetic retinopathy. The neurological causes were identified, analysed and tabulated; 39% of patients were below 20 years of age and there was 3:2 ratio of female versus male prevalence. Nearly 66% had acute visual loss and 35% had chronic visual loss. Majority of patients (48%) had profound visual loss limited to finger counting; 6% had normal visual acuity associated with field defects. The visual evoked potentials were abnormal in all cases with acute and sub-acute presentation and in some patients with sudden or chronic presentation also. The VEP abnormalities consisted of prolonged P100 latencies, loss of amplitudes or poor wave morphology. Cranial CT scan was done in 36 patients and was abnormal in 83% patients. It showed intracranial tumours in 8% patients and infarcts in another 8% patients. Cranial MRI scan was done in 12 patients and was normal in 83% patients. The aetiological considerations and treatment protocols followed are discussed. The limitations of such study in the present setup are also highlighted.
