The levels of NE and 5-HT were determined in different brain regions of the field rat and the guinea-pig under normal conditions and following cold exposure at 10 degrees C. Under normal conditions NE was found to be mainly accumulated in the midbrain while 5-HT exhibited its highest value in the pons plus medulla of both animals. Cold exposure of the field rat caused a general increase in NE concentrations while a general decrease occurred in the brain regions of the guinea-pig. 5-HT mostly decreased in the two animals. These changes in the amine levels could be related directly to the animal's response to cold.
在正常条件下以及在10摄氏度冷暴露后，测定了田鼠和豚鼠不同脑区中去甲肾上腺素（NE）和5-羟色胺（5-HT）的水平。在正常条件下，发现NE主要积聚在中脑，而5-HT在两种动物的脑桥加延髓中含量最高。田鼠冷暴露导致NE浓度普遍升高，而豚鼠脑区中NE浓度普遍降低。两种动物的5-HT大多降低。胺水平的这些变化可能与动物对寒冷的反应直接相关。
