Atypical lateralization of language predicts cerebral asymmetries in parietal gesture representations

What is it about?

One of the first fMRI studies showing clear links between the lateralization of language and gesture. Here, the links were shown in left-handers, including individuals with atypically represented functions. (The findings in right-handers are similar, as shown by later studies.)

Why is it important?

Atypical (bilateral, or right-lateralized) organization of language in inferior frontal cortex is linked to a similar atypical pattern in inferior parietal representations of familiar gestures. This relationship is consistent with the hypothesis that these fundamental behaviors exploit a common cerebral specialization.
