all the procedures induced c-fos immunoreactivity in parvocellular neurons of the paraventricular nucleus , and many of these neurons also contained corticotropin-releasing factor immunoreactivity . c-fos immunoreactivity was also observed , for example , in subpopulations of neurons in the locus coeruleus , the ventrolateral medulla oblongata , and the nucleus tractus solitarii .
