FIG. 4.

Pattern of c-Fos–positive cells after an intragastric glucose infusion in GLP-1Rc knockout mice. The number of c-Fos–expressing cells was quantified in the NTS (A) and ARC, VMH, and DMN nuclei (B) of GLP-1Rc knockout mice (as described in Fig. 1B) infused with water (□) or glucose (▪). Five mice per group were studied. No differences were noted between groups.
