Figure 3. Architectonic stages of the prefrontal cortex.

Figure 3

Diagrams showing the architectonic stages in the basoventral (a) and mediodorsal (b) prefrontal cortices. Each of these two broad cortical regions shows a gradient of laminar organization (for example, differentiation) from the most anterior to more-posterior portions of the frontal cortex. This axis of differentiation proceeds in a direction from the least-differentiated (anterior frontal regions such as area 10 and rostral area 46) to the most-differentiated cortex (posterior frontal regions such as caudal areas 46 and 8).
