Figure 4.

Total number of c-Fos-positive cells in the nTS of WT (left) and P2X-dblKO (right) mice across stimuli. Unstimulated animals had few c-Fos-positive cells in the nTS of either genotype. However, taste stimulation produced Fos-LI in a graded manner with water < NaCl < MSG in the nTS of WT animals. In contrast, Fos-LI across all stimuli (water, NaCl, and MSG) was similar in the nTS of P2X-dblKO animals. ns, Not significantly different; *, each stimulus is significantly different from all other taste stimuli and water, p < 0.05.
