The neural correlates of the verbal component of working memory
BY repeating words 'in our head', verbal material (such as telephone numbers) can be kept in working memory1 almost indefinitely. This 'articulatory loop' includes a subvocal rehearsal system2–6 andExpand
Localization of grasp representations in humans by PET: 1. Observation versus execution
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 three conditions.Expand
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
The role of the right hemisphere in the interpretation of figurative aspects of language. A positron emission tomography activation study.
We investigated cerebral activity in six normal volunteers using PET to explore the hypothesis that the right hemisphere has a specific role in the interpretation of figurative aspects of languageExpand
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
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
Is developmental dyslexia a disconnection syndrome? Evidence from PET scanning.
A rhyming and short-term memory task with visually presented letters were used to study brain activity in five compensated adult developmental dyslexics. Their only cognitive difficulty was inExpand
Anatomical variability in the cortical representation of first and second language
FUNCTIONAL magnetic resonance imaging was used to assess inter-subject variability in the cortical representation of language comprehension processes. Moderately fluent French-English bilinguals wereExpand
Shared Cortical Anatomy for Motor Awareness and Motor Control
In everyday life, the successful monitoring of behavior requires continuous updating of the effectiveness of motor acts; one crucial step is becoming aware of the movements one is performing. WeExpand
The role of age of acquisition and language usage in early, high‐proficient bilinguals: An fMRI study during verbal fluency
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 used to studyExpand
