We assessed the effects of age of acquisition and language exposure on the cerebral
correlates of lexical retrieval in high‐proficient, early‐acquisition bilinguals. Functional MRI was …

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 …

Positron emission tomography (PET) was used to localize brain regions that are active during
the observation of grasping movements. Normal, right-handed subjects were tested under …

Observing actions made by others activates the cortical circuits responsible for the planning
and execution of those same actions. This observation–execution matching system (mirror-…

PET was used to map brain regions that are associated with the observation of meaningful
and meaningless hand actions. Subjects were scanned under four conditions which …

BRAIN activity was mapped in normal subjects during passive obser-vation of the movements
of an 'alien' hand and while imagining grasping objects with their own hand. None of the …

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 …

A new diagnostic indicator of FDG PET scan abnormality, based on age-adjusted t statistics
and an automated voxel-based procedure, is presented and validated in a large data set …

We present behavioral and anatomical evidence for a multi-component reading system in
which different components are differentially weighted depending on culture-specific demands …

Language acquisition has been defined as (he result of a dedicated cerebral'organ'1 thai
becomes attuned to the processing of the native language during die first years of Life. 1" 1 …
