Popis: | The molluscan neuropeptide Phe-Met-Arg-Phe-NH2 (FMRFamide) was administered intrathecally (i.t.) to mice and their behavior was monitored for 30 min. FMRFamide induced a dramatic and dose-related (5-12 micrograms) increase in grooming-related activities compared to saline-treated controls. The grooming behavior produced by 8 micrograms FMRFamide was not blocked by simultaneous i.t. administration of 10 micrograms of the following antagonists: atropine, phentolamine, methysergide, naloxone or spantide; peripheral administration of naloxone (3.5 mg/kg, s.c.) also failed to antagonize FMRFamide grooming. These data constitute the first report that FMRFamide produces behavioral changes in mammals. |
