title: Acetylcholinesterase activity in seven brain areas and adenohypophysis during the estrous cycle.
abstract: Acetylcholinesterase activity was investigated in the adenohypophysis and 7 brain areas during the rat estrous cycle. In comparison with diestrous II, enzyme activity levels were significantly higher at proestrous in the adenohypophysis, amygdala and cerebral cortex. It is thought that endogenous estradiol and progesterone, acting independently and/or synergistically through their receptor systems, induce central acetylcholinesterase activity levels in the intact female rat.
