Effects of bilateral administration of (A) AP-5 and (B) CNQX into the rostral anterior cingulate cortex (rACC) on increases in response thresholds produced by 5µg/side morphine (mrp) administered into the parafascicular nucleus (PF). Data are plotted as the mean (+/− S.E.M.) threshold of spinal motor reflexes (SMRs), vocalizations during shock (VDSs), and vocalization afterdischarges (VADs). Asterisk (*) indicates thresholds significantly elevated above rACC/saline (sal) + PF/sal treatment (p < 0.05). Pound sign (#) indicates thresholds significantly reduced compared to rACC/sal + PF/mrp treatment (p < 0.05).
