according to recent golgi studies , hypothetical mechanisms underlying the three waves were proposed : the n3-wave was ascribed to the activities of small vertical fusiform cells in the sz or the upper half of sgs , the n1-wave to those of narrow field vertical cells which predominate in the lower half of sgs , and the p3-wave to those of wide field vertical cells whose somata are in the lower half of sgs or in the so .
