Abstract:
Recent neuropsychological and functional imaging evidence has
suggested a role for anterior temporal cortex in sentence-level
comprehension. We tested this hypothesis using event-related fMRI.
Subjects were scanned while they listened to either a sequence of
environmental sounds describing an event or a corresponding
sentence matched in meaning. Sentences produced greater activation
than environmental sounds in anterior superior temporal lobe
bilaterally and in other posterior superior temporal regions in the
left, while environmental sounds produced greater activation than
sentences in right inferior frontal gyrus and right posterior
superior temporal sulcus. The results provide support for the view
that anterior temporal cortex plays an important role in
sentence-level comprehension.
