[Potentials of individual muscle fibers evoked by stimulation of prejunctional nerve endings in healthy subjects (preliminary observations)].

Electrical responses of the single muscle fibre (SFER) by stimulation of the motor terminal nerve-endings have been investigated in normal subjects at various ages in vivo. Shape, latency, rise-time and interspike distance seem to be SFER's most interesting parameters of the functional organisation of the motor subunits and their terminal fractions. "Time" parameters of SFER are in agreement with the anatomo-functional characteristics of the excited tissues during ageing.
