Hyperfamiliarity for unknown faces after left lateral temporo-occipital venous infarction: a double dissociation with prosopagnosia.
Right hemisphere dominance in face processing is well established and unilateral right inferior temporo-occipital damage can result in prosopagnosia. Here, we describe a 21-year-old right-handed woman with acute impairment in face recognition that selectively concerned unfamiliar faces, following a focal left lateral temporo-occipital venous infarct. She was severely impaired in discerning that...
متن کاملNeurofunctional Signature of Hyperfamiliarity for Unknown Faces
Hyperfamiliarity for unknown faces is a rare selective disorder that consists of the disturbing and abnormal feeling of familiarity for unknown faces, while recognition of known faces is normal. In one such patient we investigated with a multimodal neuroimaging design the hitherto undescribed neural signature associated with hyperfamiliarity feelings. Behaviorally, signal detection methods reve...
متن کاملHyperfamiliarity for faces.
OBJECTIVE To report 4 cases of hyperfamiliarity for faces (HFF) and review 5 previously reported cases. METHODS We identified cases of HFF from PubMed search and references in prior reports. RESULTS Three of our 4 cases had pathologic findings that were most extensive in the left temporal lobe. HFF occurred after a tonic-clonic seizure (cases 1 and 3), during simple partial seizures (case 2...
متن کاملProsopagnosia: a double dissociation between the recognition of familiar and unfamiliar faces.
Two cases of a dissociation between prosopagnosia and impaired capacity to match familiar faces were studied. Recognition of familiar faces recovered in the first patient, whereas prosopagnosia persisted in the second patient despite recovery of matching unfamiliar faces and other visuoperceptive skills. This double dissociation is discussed in relation to current views of prosopagnosia.
متن کاملWidespread temporo-occipital lobe dysfunction in amyotrophic lateral sclerosis
Recent studies suggest that amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) lie on a single clinical continuum. However, previous neuroimaging studies have found only limited involvement of temporal lobe regions in ALS. To better delineate possible temporal lobe involvement in ALS, the present study aimed to examine changes in functional connectivity across the whole brain...
