Taming Brain Waves to Improve Focus and Concentration [Meditation!]
Do you know that taming brain waves to improve focus and concentration is possible and we can tremendously improve calculating, thinking and creative abilities through the same?
There are different types of brain waves created in the brain, with different electrical frequencies, depending upon the mental state of rest or activities. Electroencephalograph (EEG) can measure brain waves in the brain by using electrodes placed on head scalp. The electrical brain impulses may be detected, recorded, read and analyzed for results. The wavy EEG tells a lot of stories about what is actually going on inside brain.
Frequency of the electrical brain impulse is the number of times the wave repeats in one second. Neuro experts can analyze these frequencies and can interpret whether brain is less active or deficient, hyperactive or what time of day it was so, and how a mental performance can be effected, by just reading and interpreting the graph of the brain waves.
What are Brain Waves?
Human brain waves are oscillating fractions of electrical voltages in the brain. They are present in different parts of the brain in varying amounts. All parts of the brain not necessarily emit these waves simultaneously. Some portions are very active at a particular time, some are less active areas and some parts of brain are also found to be inactive in few individuals.
Types of Brain Waves
There are five types of brain waves identified so far which are of different frequencies and expressed in Hz(Hertz). The raw EEG describe them as frequency bands as follows:
Delta Waves (0.1 – 4 Hz)
These are lowest frequencies which occur while in deep sleep and some abnormal conditions. It is also the main rhythm in infant under one year of age and happen during third and fourth stages of sleep. Due to this slowest moving waves infants are generally disconnected through the physical world.
There is decreased delta activity during unconscious mind. We can access information during this stage of mind. Peak performers can decrease delta waves to attain high focus and peak performance. Sometimes incorrect delta wave response…
