Figure 4

(A) Scheme of viruses injected into the SC and PVN. The actual SC injection site (fluorescent latex bead accumulation) is shown as an insert underlying SC drawing.

(A2–A5) PVN parvocellular cells back-labeled from SC (green). The GFP-positive cell bodies were found in the caudal portion of the PVN and always colocalized OT (red) (A3, magnification from A2). Fibers, projecting from back-labeled PVN OT neurons to SON (arrow in A4, more caudal to A2) GFP-expressing varicouse axons in close proximity to cell bodies and dendrites of SON mag-noOT neurons (high magnification in A5) are shown. The scale bars represent 500 μm in (A2) and (A3) and 75 μm in (A4) and (A5).
