Abstract
Noninvasive stimulation of the human cortex is possible by means of electrical and magnetic brain stimulation. In 1980 and later on in 1982 Merton and Morton described a low output impedance electrical stimulator, with which central motor conduction velocity can be measured. Stimulation of the motor cortex trough the intact scalp and skull by brief high voltage stimuli can give rise to brief muscle contraction, for example, in the hand (Marsden et al., 1983).
