Abstract
Some additions/corrections are offered to Geddes, 2004. Stimulation is initiated by the second spatial derivative of the voltage along the nerve (activating function) rather than current density. Chronaxie values change with distance from the electrode. Anodic stimulation can excite via anodic break excitation, or via virtual cathodes around the anode.
摘要
对格迪斯2004年的内容有一些补充/修正。刺激是由沿神经的电压的二阶空间导数（激活函数）而非电流密度引发的。时值值会随与电极距离的变化而改变。阳极刺激可通过阳极断电刺激或通过阳极周围的虚拟阴极来激发。
