[Informative value of forms of visual evoked potentials in assessing the location of a visual tract block]

It is proposed the explanation of the form of visual evoke potential (VEP) on the base of physical imagination of the electrical field of double electrical layers that can approximate the wave of excitement of the visual tract. We mast take into consideration the electrical potential as active as indifferent electrode simultaneously and estimate visual evoke potential as diversity. It is shown on mathematical model the more smooth form of visual evoke potential under block and unimportant to arrangement of the electrode over the place of block.
