Figure 2.

Examples of labeling of the cranial ganglia. (A) Following injection of the ciliary body with rabies virus, brown labeled cells were evident throughout the ciliary ganglion (CG). (Box indicates area shown in [B].) (B, C) Higher-magnification views show the largely unbranched dendrites and small perisomatic processes of the labeled ciliary ganglion cells (box in [B] indicates area shown in [C]). No labeled ganglion cells are apparent in the superior cervical ganglion (SCG) (D), pterygopalatine ganglion (PPG) (E), or trigeminal ganglion (TG) (F). Scale bar for A and D is shown in F.
