Abstract

In anesthetized rabbits, extracellular recording of activity of 236 neurons was made in the anterior hypothalamus on changing of its temperature (+/-3 degrees C). 27% of the neurons revealed high sensitivity to the temperature stimulus with coefficient Q10 from 2.4 to 30; 6% of the neurons reacted by the on-response type; 5% of the neurons changed their activity and preserved the new level. The character of the unit responses seems to indicate that the anterior hypothalamus fulfills not only the reception of temperature shifts, i.e. the primary processing of information, but its further analysis as well.

摘要

在麻醉的兔子身上,在前下丘脑温度变化(±3摄氏度)时对236个神经元的活动进行了细胞外记录。27%的神经元对温度刺激表现出高敏感性,Q10系数在2.4至30之间;6%的神经元以开反应类型做出反应;5%的神经元改变了它们的活动并维持新的水平。单位反应的特征似乎表明,前下丘脑不仅负责接收温度变化,即信息的初级处理,还负责对其进行进一步分析。
