Is there a substantial body of research supporting the phenomenon of light/sound (L/S)? Certainly, the field is growing rapidly and, as a result of the proliferation of the newer commercial devices, a rash of anecdotal reporting has found its way into the popular press. Hutchison (1990) devoted almost the entire issue of volume 1, number 2 of his exciting journal, MEGABRAIN REPORT, to a discussion of L/S, including very early reports. With all due respect, we will borrow some of this material although we urge you to subscribe to this extremely informative newsletter/journal.

As noted by Hutchison, ancient scientists were fascinated by the phenomenon of flickering lights. Apuleius experimented in 125 A.D. with the flickering light produced by the rotation of a potter’s wheel, finding that it could reveal a type of epilepsy. Ptolemy studied in 200 A.D. the phenomenon of the flickering generated by sunlight through the spokes of a spinning wheel. He noted that patterns and colours appeared in the eyes of the observer and that a feeling of euphoria could be experienced. French psychologist Pierre Janet, one of the first who reported a “rescripting” procedure (see section on Clinical Considerations), noticed that the patients at Salpetriere Hospital in Paris experienced reductions in hysteria and increased relaxation when exposed to flickering lights…
