Language ROIs mixed between hemispheres

We developed a new approach that assesses laterality of certain circuitry by calculating seedmaps using ROIs that involve n left-hemisphere (LH) and m right-hemisphere (RH) grayordinates, where n+m equals the total size of the original ROI. In essence, n grayordinates are randomly removed from the LH and added to the RH. This is done for each value of n 10 times to create different source ROIs to sample from. This project was done to study the language network, and so we publish three sets of ROIs: for "Broca's area" (inferior frontal gyrus), middle temporal gyrus, and a "Wernicke's area" near the temperoparietal junction. These ROIs were generated from the ventral attention network atlas published at neuroatlas.org.
