Capsinoid administration increases neuronal activation in the nodose ganglion. a-b: Nodose ganglia from mice given IP administration of capsinoids (a) or vehicle (b). c: Increased magnification of the numbered circles in a and b. Yellow circles represent example c-Fos positive neurons, red circles represent example c-fos positive non-neurons, white circle represents example c-fos negative neurons. d: Summary and statistical comparison of total c-fos positive neurons between capsinoid- and vehicle-administered mice. (**: p < 0.01).
