Parvocellular and magnocellular divisions of the PVN. Photomicrographs of coronal sections through the brain at the level of the paraventricular nucleus (PVN) following sham (a) or acute myocardial infarction (MI; b). c, d High magnification of the PVN, illustrating the division of the parvocellular (yellow) and magnocellular (ref) regions. Black staining indicates c-Fos-positive nuclei. e A bar graph quantifying the number of c-Fos-positive cells in the parvocellular division of the PVN for sham (n = 8) and MI rats (n = 8). All data are presented as mean ± SEM. ***P < 0.001 vs sham, unpaired t-test. Scale bars = 50 μm
