Photomicrographs of the lateral septum. Taken from coronal sections located ∼0.70 mm anterior to bregma showing Fos expression in representative rats from groups CONTROL-SAL (a), CONTROL-MDZ (b), CAT-SAL (c), and CAT-MDZ (d). Note the high levels of Fos expression produced by cat odor exposure in c and the reduction in produced by midazolam evident when comparing c and d. Scale bar, 500 μm. For location of brain region corresponding to these photomicrographs, see Figure 1, region 8. LSV, Lateral septum (ventral part); LV, lateral ventricle; aca, anterior commisure.
