The catecholamines and serotonin contents in different brain areas were studies in rats under hypothermia of 30 degrees and 20-19 degrees C and in Citellus pigmaeus Pallas on the 7th, 15th and 30th day after hibernation. The artificial and natural drop in the body temperature is shown to increase the catecholamines and serotonin contents in cerebral hemispheres, cerebellum, thalamus, hypothalamus and medulla oblongata. A long artificial cooling is accompanied by a decrease in the value of the catecholamines/serotonin ratio in the brain due to an increase in the serotonin content and a long hibernation by redistribution of the content both of catecholamines and serotonin without changing their ratio.
对处于30℃以及20 - 19℃低温状态下的大鼠，以及对冬眠后第7天、第15天和第30天的五趾跳鼠大脑不同区域中的儿茶酚胺和5-羟色胺含量进行了研究。结果表明，体温的人工降低和自然降低均会使大脑半球、小脑、丘脑、下丘脑和延髓中的儿茶酚胺和5-羟色胺含量增加。长时间的人工降温会导致大脑中儿茶酚胺/5-羟色胺比值下降，原因是5-羟色胺含量增加；而长时间的冬眠则会使儿茶酚胺和5-羟色胺的含量重新分布，但它们的比值不变。
