Some human capabilities are amazing, including the ability to manipulate their brain waves. This means that we actually have the right to choose what we want to feel: We can choose - or not - to be happy, sad, stressed and also set our brain condition in order to quickly learn new abilities.
As already mentioned above, that based on the examination in many research center and laboratory related to human brain function research. Human brain activities can be checked, monitored, or can even be recorded using the equipment called EEG (electroencephalogram) and also brain mapping.
While the EEG (electroencephalogram), which examined, monitored and recorded is frequency, signal and brain wave, which then put in "classification" right into a state of consciousness, unconsciousness, and sleep (dream state). Vibration or frequency is the number of pulses (impulse) per second with units of Hz (kHz or MHz).
Based on research for many years, especially in-America, Europe and also in Asia that vibration / frequency of the brain (central nervous) in humans, is different for each phase (conscious, light sleep, deep sleep / deep, trance / trance, panic), so some experts in the field of psychology / psychiatry, (neurophysiologic) and neurologist make a commitment and covenant as follows:
Brain Vibration / Frequency:
• Gamma : 16 Hz - 100 Hz
• Beta : > 12 Hz
• SMR (Sensory Motor Rhythm) : 12 Hz - 16 Hz
• Alpha (Berger's wave) : 8 Hz - 12 Hz
• Theta : 4 Hz - 8 Hz
• Delta : 4 Hz - 0.5 Hz
Actually, the overall frequencies are join randomly and interfere with each other, but with the EEG, the frequency of these waves can be analyzed and described one by one with a note that when measured, where the most dominant frequency, and has the highest amplitude, that is considered and remains in this phase , whether the phase of Beta, Alpha, Theta or Delta, and so on.
