Abstract
Role of Entrainment in Rehabilitation
Highlights
Entrainment is an interesting phenomenon in biological systems
Schumann Resonance is the result of these oscillations and the resonance frequency falls within the alpha range of the brain waves
When a flashing light in the field of view of a person is close to alpha frequency of EEG, for example, the brain waves tend to lock to this external signal! The experiment is similar to Neuro feedback systems; the difference being in EEG entrainment, a light source in the visual field of the person is driven at around alpha frequency
Summary
Entrainment is an interesting phenomenon in biological systems. This is a process through which two signals that are close to each other in frequency get entangled into a single frequency. Two pendulums connected to a common support bar move quickly toward entrainment. One of the most common entraining signal sources is the so-called Schumann Resonance (SR). This resonance occurs as electromagnetic waves bounce back and forth between the surface of the earth and the ionosphere. It is thought that this resonance is essential for normal human activity; it is possible that entrainment of biological signals between humans could be understood on the basis of Schumann Resonance [1]
