Classification of primary progressive aphasia and its variants
This article provides a classification of primary progressive aphasia (PPA) and its 3 main variants to improve the uniformity of case reporting and the reliability of research results. Criteria forExpand

Sensitivity of revised diagnostic criteria for the behavioural variant of frontotemporal dementia.
Based on the recent literature and collective experience, an international consortium developed revised guidelines for the diagnosis of behavioural variant frontotemporal dementia. The validationExpand

Listening to Action-related Sentences Activates Fronto-parietal Motor Circuits
Observing actions made by others activates the cortical circuits responsible for the planning and execution of those same actions. This observationexecution matching system (mirror-neuron system) isExpand

Dyslexia: Cultural Diversity and Biological Unity
The recognition of dyslexia as a neurodevelopmental disorder has been hampered by the belief that it is not a specific diagnostic entity because it has variable and culture-specific manifestations.Expand

Early Setting of Grammatical Processing in the Bilingual Brain
The existence of a "critical period" for language acquisition is controversial. Bilingual subjects with variable age of acquisition (AOA) and proficiency level (PL) constitute a suitable model toExpand

A cultural effect on brain function
We present behavioral and anatomical evidence for a multi-component reading system in which different components are differentially weighted depending on culture-specific demands of orthography.Expand

The bilingual brain. Proficiency and age of acquisition of the second language.
Functional imaging methods show differences in the pattern of cerebral activation associated with the subject's native language (L1) compared with a second language (L2). In a recent PETExpand

Bilingualism tunes the anterior cingulate cortex for conflict monitoring.
Monitoring and controlling 2 language systems is fundamental to language use in bilinguals. Here, we reveal in a combined functional (event-related functional magnetic resonance imaging) andExpand

The logopenic/phonological variant of primary progressive aphasia
Objective: Primary progressive aphasia (PPA) is characterized by isolated decline in language functions. Semantic dementia and progressive nonfluent aphasia are accepted PPA variants. A “logopenic”Expand

The neural correlates of verb and noun processing. A PET study.
The hypothesis that categorical information, distinguishing among word classes, such as nouns, verbs, etc., is an organizational principle of lexical knowledge in the brain, is supported by theExpand
