Artifact reduction in magnetic stimulation.
A new biopotential amplifier is described in which the stimulus artifact from recordings of electrically or magnetically evoked biopotentials is minimized by a special active filter. The amplifier is tested in different experiments and the recordings are compared to standard EMG recordings.
