Strategy selection and the effects of muscimol treatment and estrous cycle stage. (Top) Strategy biases across the estrous cycle in saline-treated rats. Note that significant differences between groups appeared with proestrous rats using a place strategy and estrous rats using a response strategy. Diestrous rats demonstrated no strategy bias. (Middle, bottom) Low (middle) and high (bottom) muscimol treatment shifted strategy use toward response. ^*P < 0.05 within group; #P < 0.05 between estrous cycle groups within treatment; +P < 0.05 relative to saline controls.
