Figure 4. From: A neuronal morphologic type unique to humans and great apes.

Comparison of spindle cell volume with relative brain volume (see refs. 19 and 20). There is a strong correlation between the volumes of these neurons and brain volume residuals. No such correlation existed for pyramidal and small fusiform neurons of layers V and VI.

Figure 2. From: A neuronal morphologic type unique to humans and great apes.

High-magnification computer-generated maps of the localization of spindle neurons in layers V of the anterior cingulate cortex in orangutan (A), gorilla (B), common chimpanzee (C), bonobo (D), and human (E). Spindle cells are represented by solid marks, and the neighboring pyramidal neurons are represented by open triangles. Note the differences in the densities of these neurons among species and the clustered pattern in bonobo and human. AC are 1-mm wide and D and E are 1.5-mm wide.

Figure 1. From: A neuronal morphologic type unique to humans and great apes.

Morphology of spindle cells in layer Vb of the anterior cingulate cortex in human (A), bonobo (B), common chimpanzee (C), gorilla (D), and orangutan (E). In all of these species the spindle cells display similar morphology and apparent somatic size. Note the clusters of spindle cells in the through-focus photomontage from the human and in the bonobo, whereas isolated neurons are observed in the three other great apes. (F–H) No spindle cells are present in the anterior cingulate cortex of the white-handed gibbon (F), Patas monkey (G), or ring-tailed lemur (H). [Bar = 50 μm (A), 80 μm (B–E and H), and 120 μm (F and G).]

Figure 3. From: A neuronal morphologic type unique to humans and great apes.

Computer-generated maps of the distribution of spindle neurons in the anterior cingulate cortex. All maps show a level situated at the genu of the corpus callosum in the human (A), bonobo (B), common chimpanzee (C), gorilla (D), and orangutan (E). The spindle cells are restricted to layer Vb and show much higher numbers in human and the two chimpanzee species, whereas fewer are seen in gorilla and orangutan. No spindle cells are observed in the white-handed gibbon (F), long-tailed macaque monkey (G), and owl monkey (H). The maps are approximately to scale. The darkly shaded areas in B reflect local damage to the superficial layers of the specimen. The caudate nucleus is shaded darkly in H. CC, corpus callosum; CS, cingulate sulcus.
