Abstract

Changes in extracellular unit activity of 236 neurons of the medial preoptic and septal regions to local temperature stimulation were studied in acute experiments on rabbits anesthetized with urethane and chloralose. Of this total number of neurons 27% were highly sensitive to changes in brain temperature (15% to heat, 12% to cold). Altogether 6% of neurons gave an on-response and 5% a prolonged after-effect to temperature stimulation. The possible role of these neurons in the regulation of temperature homeostasis is discussed.

摘要

在使用乌拉坦和氯醛糖麻醉的家兔急性实验中,研究了内侧视前区和隔区236个神经元的细胞外单位活动对局部温度刺激的变化。在这总数的神经元中,27%对脑温变化高度敏感(15%对热敏感,12%对冷敏感)。总共有6%的神经元对温度刺激产生开反应,5%产生延长的后效应。讨论了这些神经元在体温稳态调节中的可能作用。
