Ro 10-5824 (3 mg/kg) increases the success rate in the ORD task. At doses of 1 and 3 mg/kg, Ro 10-5824 increases baseline gamma band activity in the frontal cortex. Ro 10-5824 has no effect on spontaneous locomotion^[1]. RO-10-5824 (10.0 mg/kg) does not increase center entries in the open field in a single 60-min session without the novel object present, nor does it increase overall transitions in the initial experiment with C57 mice^[2].
