Response thresholds following bilateral morphine (5 µg/side) administered into sites outside the anatomical boundaries of the parafascicular nucleus (extra-PF). Thresholds following morphine (mrp) administration were compared to those attained following saline (sal) administration into the rostral anterior cingulate cortex (rACC) and 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/sal + PF/sal treatment (p < 0.05). Pound sign (#) indicates thresholds significantly lower compared to rACC/sal + PF/mrp treatment (p < 0.05).
