The Role of the Periaqueductal Gray in the Modulation of Pain in Males and Females: Are the Anatomy and Physiology Really that Different?
Figure 2
(a)–(c) Distribution
of cells retrogradely labeled (FG+) from the RVM in males
(left) and females (right) at three representative rostrocaudal levels of the
periaqueductal gray. Each black circle represents one FG+ cell. (d)–(f) Distribution
of PAG cells that were immunoreactive for AR (closed circles) or ER (open circles). (g)–(i) Distribution
of PAG cells retrogradely labeled from the RVM that
were also immunoreactive for AR (closed stars) or ER (open stars).
