[Electromagnetic stimulation of the nervous system. I. Normal values in the central nervous system and a comparison with electric stimulation].

After non-invasive stimulation of the motor cortex by brief electromagnetic pulses evoked potentials were biolaterally recorded in 29 healthy individuals. Normal values for the following target muscles were calculated: abductor pollicis brevis (APB), biceps brachii (BIC), tibialis anterior (TIB) and extensor digitorum brevis (EDB). In a subgroup (N = 12) results for APB and EDB were compared with those obtained by electrical stimulation techniques.
