The purpose of this paper is to obtain an electrophysiological evaluation of visual field defects consecutive to the direct lesion of optic radiations in drug-resistant epileptic patients after a standard electrocorticographically adjusted lobectomy, and to correlate it with conventional perimetric results, and with the volume of resected tissue during… (More)
A discussion is presented of the main features of grating coding when the encoder ruling has unequal widths in clear and dark bars. It is shown that the use of such a grating does not alter difference information. Alterations occur on the addition information. The validity of this analysis for the partially coherent case is shown.
