Asymmetry in intra-hemispheric intrinsic connectivity, and its association with handedness and
hemispheric dominance for language, were investigated in a sample of 290 healthy volunteers enriched in left - handers (52.7 %).
Functional MRI (fMRI) studies employing similar violation paradigms have also reported differential responses in the bilateral inferior frontal gyri (sometimes with a right -
hemispheric dominance) 18,22,23,24,25,26,27, and the anterior insular cortices22, 23,27.
In addition, we investigated the relationship between asymmetry in intra-hemispheric intrinsic connectivity and language
hemispheric dominance, including a potential effect of handedness on this relationship, thanks to an FMRI acquisition during language production from which an hemispheric functional lateralization index for language (HFLI) and a type of
hemispheric dominance for language, namely leftward, ambilateral, or rightward, were derived for each individual.
These findings demonstrate that handedness and
hemispheric dominance for language are significantly but independently associated with the asymmetry of intra-hemispheric intrinsic connectivity.

Kudrow graduated from Vassar College with a degree in biology, and after graduation began working with her father — a world - renowned headache specialist — on a study concerning
hemispheric dominance and headache types.
