In the European hamster, Cricetus cricetus, a common hibernator, over a year, the gamma-aminobutyric acid (GABA) content has been followed, in the cytosolic and crude synaptosomal fractions of the olfactory bulbs, hypothalamus and cerebellum. In these 3 areas, the GABA content shows circannual variations of endogenous origin: in this period, in both fractions two peaks can be observed, at the beginning of spring and in autumn. These circannual variations do not follow the circannual variation of food intake or body weight.
在欧洲仓鼠（金黄仓鼠，一种常见的冬眠动物）中，对嗅球、下丘脑和小脑的胞质和粗制突触体部分的γ-氨基丁酸（GABA）含量进行了为期一年的跟踪研究。在这三个区域，GABA含量呈现内源性的年周期变化：在此期间，两个部分在春季初和秋季都可观察到两个峰值。这些年周期变化并不跟随食物摄入量或体重的年周期变化。
