The most selective disorder of central conceptual knowledge arises in semantic dementia, a
degenerative condition associated with bilateral atrophy of the inferior and polar regions of …

Semantic memory encompasses knowledge of objects, facts and words. A number of brain
regions are probably involved, but the left infero-lateral temporal lobe appears to play a key …

The anterior temporal lobe (ATL) is thought to be critical for semantic memory–our
knowledge of objects, people, words, and facts. However, there is substantial disagreement …

Semantic dementia, a circumscribed disorder of semantic knowledge, provides a unique
model for understanding the neural basis for semantic representation. The study addressed …

Studies of semantic dementia and PET neuroimaging investigations suggest that the
anterior temporal lobes (ATL) are a critical substrate for semantic representation. In stark …

Studies of patients with semantic impairments following brain damage offer key insights into
the cognitive and neural organization of semantic memory. Especially important in this …

Disorders of semantic cognition in different neuropsychological conditions result from
diverse areas of brain damage and may have different underlying causes. This study used a …

Background: Left posterior middle temporal gyrus (pMTG) is reliably activated in functional
neuroimaging studies of semantic processing and is frequently damaged in patients with …

Different neuropsychological populations implicate diverse cortical regions in semantic
memory: semantic dementia (SD) is characterized by atrophy of the anterior temporal lobes …

Semantic memory is a crucial higher cortical function that codes the meaning of objects and
words, and when impaired after neurological damage, patients are left with significant …
