Abstract
- The action of the venom of the wasp Campsomeris sexmaculata on the insect CNS has been studied using the cercal nerve-giant interneuron preparation of the sixth abdominal ganglion of the cockroach. 2. The venom blocks synaptic transmission either transiently (at low concentration) or for a long time (at higher concentration), and causes a permanent depolarization of the neuron with a delay. 3. The venom does not affect directly the axonal excitability.
摘要
- 利用蟑螂第六腹节神经节的尾须神经-巨中间神经元标本，研究了六斑大土蜂毒液对昆虫中枢神经系统的作用。2. 该毒液能短暂地（低浓度时）或长时间地（高浓度时）阻断突触传递，并延迟导致神经元永久性去极化。3. 该毒液不直接影响轴突兴奋性。
