Figure 3

Color photomicrographs demonstrate the spatial relationship between mPFC-LC projecting fibers and DBH labeled LC (circled by dashed lines) in coronal sections. The left column shows DBH labeled LC profiles from rostral to caudal (A1-A3; Cy2: green). The middle column exhibits FR anterogradely labeled mPFC-LC projecting fibers and also a few FR retrogradely LC-mPFC projection neurons (B1-B3; red). The right column shows the merged photos. Note that the majority of mPFC-LC projecting fibers are located in the rostral sector of the LC, especially the rostromedial Peri-LC (marked by arrows in upper row), and very few fibers can be identified in the intermediate and caudal levels. In addition, a few FR labeled LC-mPFC projection neurons are noticed throughout all LC levels (marked by arrow heads). Scale bar: 30 μm.
