Extended Data Fig. 1: The Interhemispheric Fibers Connecting Bilateral Face ROIs.

From: Multimodal mapping of the face connectome

Extended Data Fig. 1

Probabilistic tractography indicated that bilateral posterior ROIs (EVC, OFA, FFA, STS and PCC) are connected through the splenium of the corpus callosum whereas bilateral frontal ROIs are connected through the genu (IFG) or rostrum (OFC) of the corpus callosum. Bilateral ATLs have two separate interhemispheric connections, either via the splenium of the corpus callosum (by climbing up posteriorly along the temploral lobe) or the anterior commissure. Each amygdala is connected to the other by the anterior commissure. These findings accord well with previous work on the callosal fiber organization 118, AMG/ATL interhemispheric connections 119, and EVC interhemispheric connections which begin at the boundary of V1 and V2 120–122. Upper row: medial views; Lower row: axial views. Abbreviations: EVC: early visual cortex; OFA: occipital face area; FFA: fusiform face area; ATL: anterior temporal lobe; STS: superior temporal sulcus; IFG: inferior frontal gyrus; AMG: amygdala; OFC: orbitofrontal cortex; PCC: posterior cingulate cortex.
