What is the electrial test chronamimetry used for? what is a normal chronaxie? How long does it take for a neuron to degenerate(wallerian degen). Chronaximerty tests for electrical excitability of perpheral N. The chronaxie value is the amount of time that the current musht be on in order to produce a min contraction. Normal value is <1ms. it takes 7-10 days for neurons to degenerate.
