MECHANICAL, THERMAL AND OPTICAL SIGNS OF EXCITATION IN THE NERVOUS SYSTEM

我们继续并扩展了对非电刺激征兆的记录 神经系统中的过程。我们发现背部的浑浊程度 青蛙脊髓柱对电刺激的反应增加 应用于背根。我们得到的记录显示， 由传入脉冲引起的脐带温度。接下来，我们演示了 青蛙视网膜中无长突细胞和神经节细胞的树突 对光刺激的反应是缓慢的收缩。最后，我们分析了 视网膜中以产热为基础的光诱导事件序列 一种索引。目前正在试图阐明这些疾病的性质。 神经系统中新发现的机械和热现象。

We continued and expanded recording of non-electrical signs of excitation processes in the nervous system. We found that the turbidity of the dorsal column of the frog spinal cord increases in response to electric stimuli applied to the dorsal roots. We obtained records showing a rise of the temperature of the cord evoked by afferent impulses. Next, we demonstrated that the dendrites of the amacrine and ganglion cells in the frog retina respond to light stimuli with slow contractions. Finally, we analyzed the sequence of light-induced events in the retina by taking heat production as an index. Attempts are now being made to elucidate the nature of these newly discovered mechanical and thermal phenomena in the nervous system.
