Neural Mechanisms That Underlie Angina-Induced Referred Pain in the Trigeminal Nerve Territory: A c-Fos Study in Rats
Figure 3
A comparison of the number of Fos-labeled cells across uninfused control (Control, ), vehicle-infused (Vehicle, ), and PPS-infused (PPS, ) rats in the left (a) and right (b) TSNC. Pr5, the principal sensory trigeminal nucleus; Sp5O, the subnucleus oralis; Sp5I, the subnucleus interpolaris; Sp5C, the subnucleus caudalis. Note that a significant increase in the number of Fos-labeled cells was only observed in both sides of the Sp5C. , significantly different from the number of Fos-labeled cells in vehicle-infused rats.
