Recorders, Graphic, Evoked Potential, Visual
Definition : Evoked potential graphic recorders that record a potential that originates in the occipital cerebral cortex in response to visual stimuli (e.g., checkerboard). These potentials are usually recorded from an electrode placed on the midline of the skull 1 to 2 cm above the inion, with a reference electrode usually on the earlobe. The resultant waveform may be used to assess lesions of the anterior visual pathways and progressive neuronal diseases.
