 Brainwave Entrainment refers to the brain’s electrical response to rhythmic sensory stimulation, such as pulses of sound or light. When the brain is given a stimulus, through the ears, eyes or other senses, it emits an electrical charge in response, called a Cortical Evoked Response (shown below). These electrical responses travel throughout the brain to become what you see and hear.
FFR can be useful because brainwaves are very much related to mental states. For example, a 4 Hz brainwave is associated with sleep, so a 4 Hz sound pattern would help reproduce the sleep state in your brain. The same concept can be applied to nearly all mental states, including concentration, creativity and many others. It can even act as a gateway to exotic or extraordinary experiences, such as deep meditation or “lucid dreaming” type states.
The aim of brainwave entrainment is to induce the brain into a specific targeted brainwave frequency. It is therefore important to understand the nature of human brainwaves and what they appear to do. EEG recordings show that there are different types of brainwaves each working on a different ‘frequency’. These frequencies are measurable in Hz in much the same way a radio signal can be measured. It is interesting to realize that the brain produces different brainwave frequencies depending upon its current activity. For example whilst in daily activity, the brain tends to operate between the frequencies of 12hz to 38hz, this frequency is know as the Beta Frequency.
