Figure 5: Horizontal and rearing activity of ovariectomized rats that received a Silastic implant with or without estradiol. Horizontal (Top Panel) and Rearing (Bottom Panel) activity on day 28 of ovariectomized rats that received a Silastic tube without or with estradiol (data combined of 3 and 4 mg estradiol).
