Figure 4

Light micrograph of oxytocin-immunoreactive fibers in the paraventricular nucleus of the hypothalamus (PVN) and nucleus accumbens (NAcc) of the prairie vole from a horizontal section. Black line delineates the boundary of the striatum as determined by a marker for KChIP2. Note the diffuse pattern of immunoreactive fibers coursing toward the striatum. A few fibers deviate from the neurohypophysial pathway of the PVN and project toward the striatum. Scale bar = 100 µm. ac = anterior commisure, f = fornix.
