Indeed, many facts tend to show that the results and functional success of certain experiments in neurophysiology and in behavioral sciences have a different outlook whether performed in a newborn or in an adult.

Certain personal clinical observations suggested the same conclusion. Long-term followup of patients born with lesions of the lower motor neuron type, mainly in Erb's palsy, but also in spina bifida^1,2 showed comparatively normal electrophysiological findings despite the prolonged atrophy and the loss of function. The electromyographic (EMG) findings were characterized by normal motor units, sometimes of low amplitude, recruited by stimulation or by . . . [Full Text PDF of this Article]
