On the slide (approx. 3:00 min) you write that myokymic discharges originate from both the muscle and the axon. Is this an oversight or are they also generated by the muscle cells?
Myokymic discharges I agree that this is a less common mechanism and therefore I did not read this word when I discussed my slide. Myokymia is the repeated contraction in the muscle detected on the surface. The generation varies. Electrophysiologically is is a subgroup under repetitive discharges or grouped discharges. Those that are seen as repetitive motor unit potentials are definitely from the axon. Those with single fiber shape (such as double discharges, CRD, ..) are from the muscle. There are situations where the generation is discussed. So, to be on the safe side, define myokymic discharges as generated in the axon, the most common. Thanks for comments.

Good, thanks
