Figure 4. LPS-induced Fos activation of forebrain vlBNST afferents.

Figure 4

Despite the presence of numerous retrogradely-labeled neurons and a relatively high incidence of Fos expression within the caudal (A) and rostral PVT (B), relatively few double-labeled neurons were observed in rats after LPS treatment. Conversely, many retrogradely-labeled neurons in the lCEA (C) and dlBNST (D, particularly prevalent within the oval subnucleus) expressed Fos in rats after LPS treatment. Arrows point out examples of double-labeled neurons. Scale bars = 100 µm.
