Figure 2. Projections from the rostral CnF to the dorsolateral PAG.

Figure 2

A, camera lucida drawings of anterograde labelling of ascending axons and terminal boutons from an injection of PHA-L in the rostral cuneiform nucleus. Series of transverse sections from posterior to anterior (Aa–f) are shown (×4 and ×10 magnification on the left and right side, respectively). Numbers indicate distance (in mm) from bregma. B, phtotomicrographs corresponding to the drawing shown in Af. PHA-L immunolabelled fibres (Ba) and varicosities (see arrows in ×20 magnification photomicrograph in Bb) in the dorsolateral PAG. Scale bars: 500 μm. For abbreviations, see Fig. 1.
