Cold produced increase in latency of the dorsal root evoked monosynaptic ventral root reflex was investigated in frog lumbar spinal cord. Attempts were made to separate changes in the synaptic transmission time from changes in the conduction velocity of axons involved in the reflex pathway. Reduction of the temperature by 10 degrees C from the initial values of about 17-19 degrees C produced a 50-60 per cent increase in reflex latency, similar to the degree of slowing down of the axonal conduction velocity. The finding fails to conclusively support the chemical synaptic transmission mechanism of the ventral root discharges studied and calls for more detailed investigation of the phenomenon.
在青蛙腰脊髓中研究了寒冷导致的背根诱发单突触腹根反射潜伏期增加的情况。尝试将突触传递时间的变化与反射通路中轴突传导速度的变化区分开来。温度从约17 - 19℃的初始值降低10℃，导致反射潜伏期增加50 - 60%，这与轴突传导速度减慢的程度相似。这一发现未能确凿地支持所研究的腹根放电的化学突触传递机制，需要对该现象进行更详细的研究。
