Multiple monopolar electrical contacts are applied to the scalp or body, using other points on the body as reference and ground. The brain muscle or other bioelectric waves conducted from each contact, relative to the reference point, are amplified, filtered, and instantaneously analyzed to produce a signal which may be perceived by the person or persons generating the bioelectric waves. This sensory feedback signal simultaneously may communicate to the generating party or parties the ongoing fluctuations in frequency, amplitude, and phase unity among two or more biological rhythms occuring within an individual, couple, or group of persons. The feedback signal may be used as an aid to establish awareness and control over the functions monitored, as an aid to meditation, as an aid to learning to flexibly and easily establish or dissolve the various states of attention and consciousness associated with the signaled characteristics of the monitored brainwaves or muscle potentials and as an aid to communicaton between neural systems within a person, i.e., lobes of the brain, muscle groups or between other nonverbal biological activities of two or more persons being monitored.
