Brain waves
Some scientists believe that mind is produced by the brain. And some others believe that mind has its own ontological reality and is capable of interacting with appropriately organized matter (brain). Currently, the mind can not be measured directly but the activity of the brain can be. Brain waves, measured by the EEG (electroencephalograph) method, can reflect the adventures of the mind. Brain waves are often divided into various regions, which correspond to particular states of consciousness:

delta: 1 - 4 Hz ... deep dreamless sleep, trance state
theta: 4 - 8 Hz ... dreaming, fantasy, imagery, creativity, meditation
alpha: 8 - 12 Hz ... relaxation, accelerated learning, body-mind integration
beta: 12 - 36 Hz ... normal wakefulness, thinking, problem solving

When ordinary consciousness is expanded into altered states of consciousness (e.g. meditation, trance, out-of-body experiences, lucid dreaming), these states are also reflected in the brain wave patterns.

Brain entrainment
It is possible to influence the brain waves by applying an external stimulus to the brain. For example, if 8 Hz vibration is applied to the brain, it will likely tend toward the state of relaxation. The phenomenon is known as frequency following response.

Binaural neurotechnology
Binaural neurotechnology applies sonic signals to entrain the brain. We usually don't hear sound frequencies below 20 Hz, which are interesting for entrainment. Therefore the binaural technique is used which applies different signals to the left and right ear. The difference is extracted by the brain audio processing mechanism as a binaural beat, and the binaural neurotechnology is utilizing this phenomenon for brain entrainment.

Neurofeedback
Neurofeedback is a brain training technique in which we train the brain to improve its ability. The brain activity is reflected in the EEG pattern, and if properly presented, the indicator can be used for a feedback loop. By challenging the brain, similarly as challenging the body in a physical exercise, we can help our brain learn to function better.
