1. A disposable cap comprising a hemispherically shaped member adapted to fit on top of a human head, the hemispherically shaped member having an exterior and an interior and further having at least nineteen electrically conducting electrodes pre-placed therein at specific positions, each of the electrodes being adapted with a metal conducting object extending through the exterior of the member for transmitting electroencephalographic signals from the human brain for analysis, the member being made of an insulating material, the member having an anterior portion divided into a left dorsal area and a right dorsal area, the member also having a posterior portion, the posterior portion having dispersed therein at least nineteen of the electrodes, said electrodes extending from the interior of the member to the exterior, means for holding said electrodes in said member, said electrodes being non-standardly arranged at positions C3, C4, F3, F4, F7, F8, FP2, FP1, P3, P4, T3, T4, T5, T6, PZ, CZ, FZ and ground, a set of fourteen of the eighteen electrodes, comprised of first and second subsets of seven electrodes each being located in the member, said set of fourteen being equally divided and dispersed in mirror-image positions in the anterior portion of the member, the first subset of seven of the electrodes being located in the left dorsal area of the member at the T4, T6, P4, F4, C4, F8, and FP2 positions, the second subset of seven of the electrodes being located in mirror image positions with respect to the first subset in the right dorsal area of the member at the T3, T5, P3, F3, C3, F3, and FP1 positions, respectively, one other of the electrodes being ground and centrally located between the right and left dorsal areas, and two additional electrodes also being centrally located between the right and left dorsal areas, wherein one is located above the ground electrode at the PZ position and wherein the other one is located below the ground electrode at the FZ position.
