<jats:p> 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 <jats:sup>-9</jats:sup> gauss (peak to peak). A course distribution shows left-right symmetry for the particular averaging technique used here. </jats:p>
