Adult female OVX Long–Evans rats approximately 90 days old were
used for all experiments. Eleven days prior to behavioralmanipulations,
animals were ovariectomized and then individually housed and maintained
on a 14/10 hour light/dark cycle. Food and water were available
ad libitum throughout the experiment. All animal procedures were
carried out in accordance with the Kent State University Institutional
Animal Care and Use (IACUC) guidelines.
