Fig. 10: Summary of differences in PMC sulcal morphology between humans and chimpanzees.
From: Sulcal morphology of posteromedial cortex substantially differs between humans and chimpanzees
Top: Inflated cortical surface reconstructions of the individual human (Left) and chimpanzee (Right) hemispheres shown in Fig. 2. Sulci: dark gray; Gyri: light gray. Individual sulci are numbered according to the key below. Note that the human hemisphere does not contain the isms (sulcus 7) or sspls-d (sulcus 9) and the chimpanzee hemisphere does not contain the prculs-v (sulcus 3) or sspls-d (sulcus 9). Bottom: Overview of differences in sulcal morphology between species. Position (right, left, both) of arrowheads indicates whether sulci increased (right), decreased (left), or remained stable (right and left) in each morphological feature between species. Left: incidence rates; Middle: sulcal depth; Right: surface area. ifrms data from ref. 24. For sulci with species-related hemispheric effects, the specific hemisphere is shown next to the sulcus in parentheses.
