 note = {An experimental study of rats on the fibrillation potential of denervation and the spontaneous electrical activity of normal muscle was carried out chiefly to find their differential key points. As the results, fibrillation potentials in denervated muscle on the 21st day after denervation were recognized to be spike potentials with the initial positive phase. But this prescription had to allow the condition that fibrillation potentials would be found only infrequently in normal muscle at rest, so quantitative consideration that these potentials should be found at least in more than two points of a muscle was taken in order to be regarded as a sign of denervation. In normal muscle, four types of spontaneous electrical activities were recognized clearly. The first type was the irregularity of the base line which was suggestive of negative monophasic activity, and provisionally named the end plate noise according to Buchthal's opinion. The second type was a spike potential with a prominent initial negative phase and called nerve potential according to Jones and supposed to be regarded not as a type of fibrillation potentials but as a normal sign. These two potentials were inferred to be dual under present conditions. The third type was fibrillation potential and the fourth type was so-called myotonic activity. The other activity was seldom found in normal muscle.},
