The problem of locating the position of the source of evoked potentials from measurements on the surface of the scalp has been examined. It is shown that the position of the source in a head modeled by a sphere surrounded by two concentric shells of

Volume conduction models of the human head have often been utilized in relating scalp potential measurements to the locus of the underlying neural sources. However, the determination of the source loci depends on the accurate location of electrodes i

We assessed the effect of amblyopic suppression on the pattern visual evoked potential (P-VEP). Since anisometropic amblyopia is associated with the monofixation syndrome and a central suppression scotoma in the amblyopic eye, patients with this func

Time-division multiplexing allows 24 channels of evoked potential data to be recorded on a seven track instrumentation tape recorder and later played back into a signal averager where it is simultaneously demultiplexed and averaged. Complimentary met

A simple circuit employing operational amplifiers yields an inexpensive low-noise biological amplifier. Design parameters are discussed and performance measured. When twenty-four of these amplifiers were incorporated in a head-mounted evoked potentia
