The effects of p-chlorophenylalanine, fenfluramine and alpha-methyltyrosine on marking responses in the male Mongolian gerbil (Meriones unguiculatus).
Marking behavior was maintained by testosterone propionate treatment in castrated Mongolian gerbils. p-Chlorophenylalanine (PCPA) enhanced and alpha-methyltyrosine (alpha-MT) inhibited responses. No effect was seen by PCPA in non-TP-treated subjects. Fenfluramine inhibited the response in intact gerbils. The data suggest that serotonergic inhibitory mechanisms exist which are implicated in testosterone dependent marking behavior in the Mongolian gerbil.
