Abstract
- Spontaneous subthreshold potentials have been recorded with an intracellular electrode from neurones of the isolated spinal cord of the frog.2. Records of both depolarizing and hyperpolarizing potentials were obtained from cells in normal Ringer solution and also when impulse conduction in the cord had been abolished by tetrodotoxin (TTX).3. Comparisons of results before and after TTX show that the majority of the spontaneous potentials are analogous to miniature end-plate potentials.
摘要
- 用细胞内电极从青蛙离体脊髓的神经元记录到了自发阈下电位。2. 在正常任氏液中以及当脊髓中的冲动传导被河豚毒素（TTX）阻断时，均从细胞记录到了去极化和超极化电位。3. TTX处理前后结果的比较表明，大多数自发电位类似于微小终板电位。
