Abstract:
:Captivity-induced stereotypies in bank voles (Clethrionomys glareolus) were inhibited at the age of 1, 2, 4, 6, 8 and 10 months by 0.2 mg/kg haloperidol s.c., while 35 mg/kg naloxone s.c. only inhibited them at the age of 4-6 months. Other activities were not significantly inhibited. The change in the naloxone effect was not due to desensitization as animals treated only at 6 or 8 months reacted similarly. It is suggested that the expression of such stereotypies is influenced by endogeneous brain opioid peptides during an early stage of their development, but that thereafter only motoric automatisms remain, essentially under dopaminergic control.
