A modified mirror projection visual evoked potential stimulator for presenting patterns in different orientations
Electroencephalography and Clinical Neurophysiology
|July 1, 1986
Abstract:
Modifications to a standard mirror projection visual evoked potential stimulator are described to enable projection of patterns in varying orientations. The galvanometer-mirror assembly is mounted on an arm which can be rotated through 90 degrees. This enables patterns in any orientation to be deflected perpendicular to their axes.
