The Brainwaves


In understanding brain functioning we refer brainwaves. The brain waves are classified on the basis of frequencies. The frequencies are the power or speed of the electrical emissions, measured as oscillations per second referred to as hertz (hz). The brainwaves are divided into Delta (1-4Hz), Theta (5-8Hz), Alpha (9-12Hz), SMR (13-15Hz), Beta (16-40Hz) and Gamma (40+ Hz).



Delta is the slowest brainwave, oscillating between 0-4 times-per-second. (0-4 Hz). When a person is in deep sleep delta is the dominant brainwave in healthy adults. Delta is characterized by high waves (high amplitude). With eye inspection the waves are relatively bigger as shown above. It is associated with the beginning of neural connectivity. We see these waves in newly born baby who spend a large part of their time sleeping.



Theta brainwaves are identified with 4-8 oscillations per second (4-8 Hz), Theta is the dominant brainwave in REM sleep, particularly in dreams or hypnosis. 



Alpha are the brain waves that runs at 9 -12 oscillations (9-12 Hz). Alpha are waves characterized by high amplitude and rhythmic are in nature. They are characterized by a relaxed and focused state of mind.



Beta brainwaves has 12 – 38 oscillation per second (12-38 Hz). These waves depict humans’ normal wakeful state. Major thinking and intellectual activities take place during this state of mind, starting with daily routine activities to higher intellectual alertness and functioning.



At the end of the session, your hair will be a little messy with paste in it. I ask clients to expect to leave the office with a little paste in their hair. This is fairly common, but something that most hair types can get away with.
