Neural networks of motor control are well understood and the motor domain therefore lends itself to the study of learning. Neuroimaging of motor learning has demonstrated fronto-parietal,… Expand
Executive Functions in Autism and Asperger's Disorder: Flexibility, Fluency, and Inhibition
The Color-Word Interference Test, Trail Making Test, Verbal Fluency Test, and Design Fluency Test from the Delis-Kaplan Executive Function System (Delis, Kaplan, & Kramer, 2001) were administered to… Expand

OBJECTIVE Autism is a neurally based psychiatric disorder, but there is no consensus regarding the underlying neurofunctional abnormalities. Previous functional magnetic resonance imaging (fMRI)… Expand
Broca's Area and the Discrimination of Frequency Transitions: A Functional MRI Study
The left inferior frontal lobe has been traditionally viewed as a "language area," although its involvement in the discrimination of rapid nonverbal frequency changes has been also shown. Using… Expand
Linguistic theory and neuroimaging evidence: an fMRI study of Broca’s area in lexical semantics
There has been a long debate on the functional characterization of left inferior frontal cortex, including proposals regarding syntactic and lexico-semantic involvement. We studied nine right-handed… Expand
