In clinical practice of Transcranial Magnetic Therapy (TMS), a very strong modulated signals is used, however research indicates that harmonics of the base resonance of the low alpha brainwave, a weak field signal is as effective if not more so than the strong signals used in clinical application. This research supports the application of the Flow Therapy device which is a personal low output TMS device.
A number of researchers and scientific publications investigated an impact of modulated EM, magnetic fields or even vibrations , see e.g. [3-10]. In 1957, German physicist Dr W. O. Schumann calculated the Earth/Ionosphere cavity resonance frequencies (which were later named after him). He fixed the most predominant standing wave at about 7.83 Hz. It has been found that the dominant brainwave rhythm of all mammals in alpha (resting) state is at a frequency of 7.83 Hz. In fact, it predominates in the hippocampus (found in the brain), which is part of the limbic system involved with emotional and memory aspects of behaviour. Suzanne Bawin, Leonard Kaczmarek and Ross Adey  at the University of California found that exposing brain tissue to weak VHF radio signals modulated at 16Hz released calcium ions bound to the surfaces of its cells. Carl Blackman at the U.S. Environmental Protection Agency in North Carolina followed this up with a whole series of experiments testing different field‐strengths and frequencies  and came to the surprising conclusion that weak fields were often more effective than strong ones. In  the influence of very weak low frequency magnetic fields between 7 and 72 Hz and amplitudes between 13 and 114 μT on the transport of Ca2+ channel protein in the cell membrane was investigated. Several frequencies such as 31.1 Hz and 24 Hz are indicated. Several old results regarding various metabolic disorders in plants and animals can be found in . Other works investigated impact of dedicated frequencies of radio-wave radiation of mm-frequency range (30-300 GHz) on living organisms. For example, radiation intensity within the limits of 0.1-1.0 mW/cm2 reveals bio-informative reaction.
Impact of ion transfer under modulated fields is closely related to electric double-layers around mesoscopic charged particles. Such double-layers are ubiquitous in many physical, geophysical, chemical and biological systems, including complex fluids, clay soils, polyelectrolytes (e.g. DNA) or cell membranes . For biological materials, such charges are mainly associated with electrical double layers occurring at membrane surfaces or around solvated macromolecules, or with polar molecules which (by definition) possess a permanent electric dipole moment . A number of publications, e.g. ,  deal with ion transfer in biological tissues, mostly cell membrane, under changed condition in electrical double layer. In   the application of an external electric field for induction of a critical electrical potential across the cell membrane is investigated. It is shown that it can lead to rapid electrical breakdown and local structural changes of the cell membrane. The work  deals with more deep issues – the stability of colloidal dispersions and the formation of bilayer membranes. The approach and fusion of biological cells, (conception, infection, recognition), the tertiary conformation of proteins, and the transport of ions and other molecules across cell membranes, are all fundamental life processes involving the electric double layer at surfaces in an aqueous environment. The work  treats properties of electric double layer interactions in bacterial adhesion to surfaces. A reappraisal of cell signalling, taking into account the protein interactions with the membrane electrostatic profile, suggests that an electrical dimension is deeply involved in this fundamental aspect of cell biology .
