The human brain emits faint electrical impulses that can be measured and recorded by EEG (electroencephalographic) monitoring devices. An EEG measurement identifies wavelengths (or frequencies) of brainwaves. 2

3. Typical EEG Tracings
A typical EEG tracing is a rapidly changing composite or combination of different frequencies—waves moving up and down at different rates—some slow, some fast. During ordinary waking consciousness, EEG patterns are complex, scattered and disorderly. 3

4. Brain waves rise and fall
EEG Coherence:
Brain waves rise and fall
in a stable pattern
High EEG coherence is seen during restful alertness.
Here we see the electrical activity from 11 points of the brain during transcending.
Top and bottom of this chart are the front left and front right parts of the brain.
Notice how the signals between pairs of sensors are rising up and down together. This is called coherence. Coherence means that two parts of the brain are talking to each other—are functionally linked.
This is global coherence.
The brain as a whole is more wakeful, is more lively.
Alpha EEG as a carrier wave for higher processing and higher EEG frequencies. The more coherent the alpha carrier wave, the more efficient the person would respond—better performance on spatial tasks, memory tasks, creativity scores and paired reaction time tasks.
Frontal alpha coherence is not reported in other meditation practices. 4

21. Maharishi has brought Vedic knowledge to the west and made it into a complete science of consciousness. His life purpose was to preserve and maintain the Vedic heritage by making it not only scientific but so easy and practical that we can use it in all field of life including education and allow every student to realise their full potential.
