Figure 2: The Golgi-Cox impregnation of neurons in the mPFC revealed the detail morphology of the stained cells.

Panel A shows a group of pyramidal neurons with distinguished shape and an apical dendrite. Panel B shows an interneuron with round body and radiating, evenly spaced dendrites of a similar size. The dendritic spines, shown in C, were classified as “stubby” (1), “long” (2), “mushroom” (3), “branched” (4) and “filamentous” (5). Scale bar = 20 μm for A and B and 5 μm for C.
