Association between precentral gyrus morphology and modality-specific intentional communication in chimpanzees (Pan troglodytes).
The precentral gyrus (preCG) is morphologically defined posteriorly by the central sulcus (CS) and anteriorly by the superior and inferior precentral sulci (preCS). Stimulation of the preCG along the dorsal-ventral plane elicits motor activation across the body in a topographic manner. In this study, we used postimage...
