Neural dynamics of semantic categorization in semantic variant of Primary Progressive Aphasia

Abstract excerpt

Semantic representations are processed along a posterior-to-anterior gradient reflecting a shift from perceptual (e.g., it has eight legs ) to conceptual (e.g., venomous spiders are rare ) information. One critical region is the anterior temporal lobe (ATL): patients with semantic variant primary progressive aphasia (svPPA), a clinical syndrome associated with ATL neurodegeneration, manifest a deep loss of seman...
