Fig. 3From: Reciprocal interactions between prostaglandin E2- and estradiol-dependent signaling pathways in the injured zebra finch brainCentral levels of estradiol (E2) content in sham animals or following bilateral brain injury in adult male and female zebra finches. Males, but not females, fail to induce E2 following EP-3 antagonism (A). Females, but not males, fail to induce E2 following EP-4 antagonism (B). Groups that do not share a letter are significantly different (p < 0.05)Back to article page
