Figure 5.

Volumes and number of neurons of the different mPFC areas and subiculum after 3 and 6 d of unpredictable stress. A, B, Average volumes of layers I, II, and III–VI of the IL, PL, and Cg regions of the mPFC and the molecular (Mol) and pyramidal (Pyr) layers of the subiculum. C, D, Estimated number of neurons in layers II and III–VI of the IL, PL, and Cg regions and the Pyr layer of the subiculum. Graphs on the left refer to animals stressed for 3 d, and those on the right refer to 6 d of stress. Control animals, n = 5; stressed rats, n = 5. Error bars represent SEM.
