Fig. 7From: The distribution of oxytocin and the oxytocin receptor in rat brain: relation to regions active in migraineOxytocin immunohistochemistry of the anterior commissure, bed nucleus and zona incerta. a. The white matter tract anterior commissure (ac) showed distinct fiber oxytocin immunoreactivity in fibers (Insert: higher magnification of ac). In addition, fibers in the bed nucleus also expressed oxytocin. b The zona incerta displayed intense oxytocin immunoreactivity in thin fibersBack to article page
