演示了人类头皮外由α节律电流产生的弱交变磁场。受试者和磁探测器被安置在多层磁屏蔽室中。采用信号平均法降低背景磁噪声。头皮附近的电场约为1 × 10-9gauss（峰对峰）。对于这里使用的特殊平均技术，航向分布显示了左右对称。
Weak alternating magnetic fields outside the human scalp, produced by alpha-rhythm currents, are demonstrated. Subject and magnetic detector were housed in a multilayer magnetically shielded chamber. Background magnetic noise was reduced by signal-averaging. The fields near the scalp are about 1 × 10-9gauss (peak to peak). A course distribution shows left-right symmetry for the particular averaging technique used here.
