Entrainment Explained

Entrainment is a process through which independent systems interact with each other. When two signals are close to each other in frequency, they fall into a single frequency. The “entraining” signal could be from inside the body or from outside. For example, an external signal, optical or acoustic, derived from electroencephalogram could drive the brain rhythms (such as α waves) to optimum values.
