1. Veratridine is often used in experiments to study the effects of neuron membrane channel activation.（Veratridine常用于实验中，研究神经元膜通道激活的效果。）

2. The researchers used veratridine to induce depolarization in the neurons and observe the resulting changes in electrical activity.（研究人员使用veratridine诱导神经元去极化，并观察所引起的电活动的变化。）
