Abstract

During hibernation reduction of frequency of the miniature end-plate potential (m.e.p.p.) was observed. This parameter was reduced in the extensor digitorum longus (EDL) muscle to 16% and in the soleus muscle to 7% of values found in awake animals. The ACh-sensitive area of the individual muscle fibres in both types of muscle increased about three times during hibernation.

摘要

在冬眠期间，观察到微小终板电位（m.e.p.p.）频率降低。在伸趾长肌（EDL）中，该参数降至清醒动物中所测值的16%，在比目鱼肌中降至7%。在冬眠期间，这两种肌肉中单个肌纤维的乙酰胆碱敏感区域增加了约三倍。
