“…Cases, however, have been reported of patients showing a significant improvement when aided with a phonological cue consisting of the first phoneme of the name. Lucchelli and De Renzi's patient TL was indeed of this type, and others have been described by Cohen, Bolgert, Timsit and Chermann (1994), Moreaud, Pellat, Charnallet, Carbonnel and Brennen (1995) and Otsuka, Suzuki, Fujii, Miura, Endo, Kondo and Yamadori (2005). Cueing with first name is, however, effective in most cases in eliciting a famous surname, given the appropriate context (as in: 'a famous actress: Marilyn?'…”

The difference between common and proper names seems to derive from specific semantic characteristics of proper names. In particular, proper names refer to specific individual entities or events, and unlike common names, rarely map onto more general semantic characteristics (attributes, concepts, categories). This fact makes the link proper names have with their reference particularly fragile. Processing proper names seems, as a consequence, to require special cognitive and neural resources. Neuropsychological findings show that proper names and common names follow functionally distinct processing pathways. These pathways are neurally distinct and differently sensitive to focal or generalized brain damage, cognitive changes with age or lack of organic resources. Their precise location, depending on specific tasks, is still partly unknown.

“…A category that is much like persons in this regard is landmarks: like persons, landmarks are unique, and they are identified by a proper name. Lesion studies had shown that patients with impaired person naming frequently demonstrated a parallel defect in naming geographical items, including landmarks (e.g., Fery, Vincent, & Brédart, 1995; Lyons, Hanley, & Kay, 2002; Otsuka, Suzuki, Fuji, Miura, Endo, Kondo, & Yamadori, 2005). Hence, a natural next step in our program of work was to study the neuroanatomical correlates of retrieving names for landmarks.…”

Background The neuroanatomical basis of lexical retrieval has been studied intensively. The current review focuses on the special case of proper nouns. Aims This article reviews a program of research that has used both lesion-deficit and functional imaging (PET) approaches to investigate the neuroanatomical basis for lexical retrieval of proper nouns. In lesion-deficit studies, we found that damage to the left temporal polar (TP) region leads to reliable and specific impairments in naming famous persons (e.g., “George Clooney”) and famous landmarks (e.g., “Golden Gate Bridge”). In functional imaging studies, we found that when participants name famous persons and landmarks, they produce specific activation (increases in regional cerebral blood flow) in the left TP region. Main Contribution These findings converge with lesion and functional imaging data from other laboratories to support the idea that the left TP region is important for the retrieval of names for unique concrete entities, persons and landmarks being typical examples of such categories of entities. Conclusions We have interpreted these results within a theoretical framework that suggests that left TP contains convergence regions that operate as intermediaries between conceptual knowledge retrieval and lexical retrieval for classes of unique concrete entities.

“…Sporadic case reports have described patients with left temporal lobe damage and proper-name anomia restricted to people's names but not associated with semantic impairment concerning people. 3,6,9,11,17,18,21) This condition could reflect disconnection from semantics to the lexical systems, although the evidence is weak. 2) On the other hand, a few cases have had proper-name anomia accompanied by semantic impairment.…”

“…5,25) Otherwise, anomia extended to common names. 17) The latter group of patients tended to have extensive lesions involving the medial and posterior temporal lobe, or the medial temporal structures had been surgically removed. Most of these patients with brain damage in the left temporal lobe showed anomia for people's names but preserved ability to retrieve common names.…”

A 47-year-old man was admitted to our hospital with an intrinsic brain tumor in the left anterior temporal lobe. Preoperative sodium thiopental test demonstrated left hemispheric dominance. Awake craniotomy was performed for dominant-hemispheric tumor resection using language mapping to identify the stimulation-induced positive language area. The tasks of object naming and repetition were used, along with specific tests for famous people's names. The language area was detected on the superior temporal gyrus and preserved. Following surgery, this patient was unable to retrieve the names of famous individuals (i.e. anomia for people's name) despite preservation of semantic knowledge for those individuals. This anomia for people's names showed no improvement at all for a period of 15 months. This case report and other sporadic cases with this type of deficit reveal the left anterior temporal lobe is an important brain area for retrieving people's names.
