METHODS: Spontaneous contraction of gastric antral circular muscle of rats was recorded by fourchannel physiograph.
方法:用四道记录仪记录胃窦环行肌条的自发性收缩活动;

Based on the module, a fourchannel module for the FES of neurons is designed for 12 sites cuff electrode or 10 sites shaft electrode.
在此基础上,设计了用于12个电极点的卡肤电极或者10个电极点的剑状电极四通道神经信号激励模块。
