Abstract— Human Brain works on small amount of electrical impulses that are produced by synaptic firing of neurons. This electrical activity has a band of frequency associated with it, for every state of mind. This band of frequency can be induced in brain using auditory and visual stimuli. The stimuli will be produced by the computer software

The brain generates a small amount of electrical activity that has varied frequency; these frequencies are divided in various bands. Although these band values are not standardised, researchers usually describe what frequency they are referring to in which band.
Frequency| Frequency Bands|
| Name| Associated state of mind|
0.5-3 Hz| Delta| Thought less Sleep|
3-7 Hz| Theta| REM Sleep|
7-12 Hz| Alpha| Relaxed, Daydreaming|
12-18 Hz| Beta| Active, Attentive|
18 – 30 Hz| High Beta| Tensed|
All of the frequencies are present all the time in the brain, but the dominant range of frequency determines the state of mind. The brain has been shown to follow the frequency of a stimuli and this phenomenon is known as Frequency Following Response and can be harnessed by the binaural beats, isochronic tones and monaural beats. BINAURAL BEATS AFFECT STATE OF MIND?
It has been observed in various studies that the entrainment is helpful in medical treatment . The CCRMA Stanford even has a group for studying the same. There have been researches that have studied the therapeutic properties of binaural beats and other form of BrainWave Entrainment.
A. Binaural Beats
When two slightly different frequencies are played separately to each ear, the...
