Hypothalamic neuropeptide Y (NPY) and serotonin (5-HT)-containing neurons are believed to exert an interactive effect on ingestive behavior. The present study examined the ability of two serotonergic antagonists, spiperone (SPIP), a 5-HT2A antagonist, and mianserin (MIAN), a 5-HT(2A/2C) antagonist, to block the inhibitory action of the 5-HT(2A/2C) receptor(More)
The number, amplitude, duration, and bout structure of isolation-induced ultrasonic vocalization (USV) of infant rats (Rattus norvegicus) were measured on postnatal Day 10. Measurements were made before and after a brief, 1-min, active interaction with their mother or before and after a "pick-up" control procedure. Consistent with prior studies, the number(More)
Two experiments tested the effects of lactation and weaning on heart rate (HR), corticosterone, and behavioral responses to stress in Wistar rats. In Experiment 1, HRs in lactating, weaning, and control animals were recorded for 10-min periods before, during, and after immobilization stress. Compared with control animals, lactating and weaning animals(More)
