Cholinergic mechanisms in scent marking behavior by Mongolian gerbils (Meriones unguiculatus).

摘要: Abstract The Mongolian gerbil reared in Japan manifested scent marking behavior the similar behavioral topography as described by foreign researchers. frequency of was affected early isolation housing; isolated male gerbils exhibited a higher than aggregated males. suppresed scopolamine (1.5 mg/kg, IP), whereas methylscopolamine ineffective. In order to elucidate possible neural mechanisms, acetylcholinesterase (ACh-E) and choline acetyltransferase (Ch-Ac) activities were measured 8 discrete areas brain (the cortex, striatum, amygdala, hypothalamus, midbrain, hippocampus, olfactory bulbs, pons plus medulla oblongata). There was, however, no significant difference between either ACh-E or Ch-Ac activity any areas. These results suggest that other events, such changes ACh turnover rate release, may participate manifestation behavior.
