FIGURE 5.

Systematic and gradual variation of laminar structure across areas of the parahippocampal trend in the human prefrontal cortex: Dorsolateral prefrontal areas. (A,B), Medial (A) and lateral (B) views of the left hemisphere from the brain (case HCD): red lines show the planes of separation of coronal slabs; black and white arrows indicate laminar differentiation along the parahippocampal trend. (C–G) Micrographs of the dorsolateral prefrontal cortex in Nissl stained sections at the levels indicated in (B); the areas according to the Atlas of von Economo and Koskinas (1925/2008) and the cortical type are indicated below each micrograph; see the text for description of laminar features. S1, S2, S3, S4, S5, indicate coronal slabs from anterior to posterior; WM, white matter. Roman numerals indicate cortical layers. Calibration bar in (G) applies to (C–G).
