Question

What are Brain Waves?

Answer 1

The brain is the most complex part of the physical body. This three-pound organ is that seat of the intelligence and the interpreter of the senses and the initiator of body movement, and controller of behavior. Lying in its bony shell and washed by the protective fluid, the brain is the source of all the qualities which outline our humanity.

Complete answer:
Brain waves are the rhythmic variations within the potential between different parts of the brain as visible on the EEG (electroencephalogram – test detecting electrical activity within the brain with the assistance of metal discs). So as to live brain waves, electrodes are found out within the scalp using the electroencephalogram.
The different sorts of brain waves are –
Alpha, Beta, Theta, Delta.
Brain waves are so essentially the evidence of our electrical activity produced by your brain. When a gaggle of neurons sends a burst of electrical pulses to a different group of neurons, it creates a wave-like pattern. These waves are now measured in the speed cycles of per second, which we describe as the Hertz (Hz).
There are four brainwave states that range from the high amplitude, low frequency delta to the low amplitude, high frequency beta. These brainwave states range from deep dreamless sleep to high arousal. An equivalent four brainwave states are common to the human species.

Note:
Brain waves are patterns of electrical activity occurring within the brain. Because brain activity is often influenced and altered through neuron feedback, desirable brain activity is often increased in those that are experiencing symptoms of certain psychological state conditions.
