Different Methods Applied in NFT
Amplitude or Power Training: refers to the amount of power in a signal or the amplitude of a particular frequency band. There may be an excess of a frequency range that is inhibited or a lack of a frequency range that is rewarded during the training.
Z-score Training: The use of z-scores implements the concept of a normal distribution or standard deviation pertaining to the increase and decrease of amplitudes in all the frequency bands relative to persons of the same age.
ISF: Focuses on the lowest energy that the brain produces (<0.1Hz). Research indicates that it regulates autonomic functioning and regulates the vagal nerve, which is the 10th cranial nerve and longest cranial nerve.
Through ISF training the optimal frequency of each person is determined and trained to become more prominent. Finding the correct frequency for a radio station is a good analogy to finding the optimal frequency of a person. When a radio is not tuned onto the correct frequency of a station it will distort the sound. If a person is not functioning at his optimal level functional deficits are present.
The optimum frequency is reflected to the trainee with 2 reward sounds. A higher tone is heard when the amplitude increases with more than 15 % above the mean (0.0030 Hz) and a lower tone is heard when the amplitude decreases with more than 15% below the mean (0.0030).
Alpha-Theta Training: The purpose of Alpha-Theta training is to reach the deeper inner state of the brain, the midbrain, and the reptilian brain, to obtain calmness and relaxation, and to enhance change of the level of awareness.
