MIND GYMS This research describes and assesses

The findings of this examination are presented in the context of six topical areas of interest. These areas of interest are (1) the scientific principles upon which the synchronized soundandlight machines are said to be based, (2) the characteristics of the machines on the market, (3) the claims made both for and against the machines, (4) the validity of the claims, (5) legal issues involving the Food and Drug Administration (FDA) surrounding the sales and use of the machines, and (6) the demand for and use of the machines.

As the brain functions, it "emits energy waves in four frequency ranges called wave states: beta, which is the normal, alert state; alpha, a slower pace noted when people are relaxed and creative; theta, the level just before people doze off, when intense learning can occur; and delta, which is deep sleep" (Williams, 1990, p. 45). Medical research found that changes in brain states may be induced through the control of audio and visual pulse

educe the frequency of headaches, (18) improve circulation, (19) grow hair, and (20) stimulate the growth of brain cells (Hooper, 1989, pp. 26, 72; Otis, 1989, p. 32). The presence in the literature of such wideranging claims of beneficial outcomes is in itself sufficient to cause many people to be skeptical of the synchronized soundandlight machines. Potentially negative outcomes are also attributed to the machines. These negative outcomes include (1) risks for epileptics, borderline personalities, and wearers of cardiac pacemakers, (2) anxiety attacks, and (3) the creation of a dependence by some individuals on the machines in order to relax (Hooper, 1989, p. 72; Fitzpatrick, 1990, p. 164; Goss, 1990, p. 22). Further, detractors hold that the alpha wave states created by the synchronized soundandlight machines can be produced much more easily by simply shutting one's eyes and sitting quietly (Otis, 1989, p. 33). Some of these negative outcomes could expose both the manufacturers of the machines, and the institutional operators of such machines to legal liability claims. Validity of the Claims For and Against Synchronized SoundandLight Machines Little scientific research has been performed to test specifically
