माझी "Music Therapy" वरची लेखमाला आठवते ना ? त्यात मी विविध "Neurotransmitters" चा उल्लेख केला होता.या लेखात "Binaural Beats" ची माहिती सांगतो. नसलीला नक्की आवडेल.

1."A binaural beat" is an illusion created by the brain when you listen to two tones with slightly different frequencies at the same time.

2.Your brain interprets the two tones as a beat of its own.

3.The two tones align with your brain waves to produce a beat with a different frequency. This frequency is the difference in hertz (Hz) between the frequencies of the two tones. 

For example, if you are listening to a 440 Hz tone with your left ear and a 444 Hz tone with your right ear, you would be hearing a 4 Hz tone.

4.When you listen to binaural beats, your brain activity matches the frequency set by the frequency of the beat. This is called the frequency-following effect. This means you can use binaural beats to entrain your mind to reach a certain mental state.

5.The superior olivary complex and binaural beats. Located in the brain stem, the superior olivary complex is the first part of the brain that processes sound input from both ears.The superior olivary complex synchronizes various activities of the many neurons in the brain. This complex responds when it hears two close frequencies and creates a binaural beat, which changes the brain waves. The synchronization of the neural activities across the brain is called "entrainment".

6.Entrainment isn’t just related to binaural beats. It is a common part of brain function. According to some researchers, when you listen to certain binaural beats, they can increase the strength of certain brain waves. This can increase or hold back different brain functions that control thinking and feeling.

7.Neurons in your brain use electrical signals to create thoughts, emotions, and behaviors. When neurons synchronize, this creates brain waves. Brain waves can be measured by a technique called electroencephalography (EEG). This technique involves electrodes put on the scalp to record electric signals. 

8.Brain waves can range from low frequency to high amplitude and high frequency to low amplitude. The brain waves create binaural beats. This leads to different mental states which affect the brain in different ways.
