What are alpha waves?

wave alpha are one type of brain wave that can be recorded by electroencephalograph (EEG). The predominance of the alpha waves in the formula of the brain wave suggests that the individual is in a relaxed but conscious state. Other types of brain waves include the waves of beta, theta and delta, each pointing to a different state of the brain. In addition to these basic types of brain wave patterns, there are other electrical signatures generated by the brain, such as "rupture" or "spindles" that occur briefly.

The nerve endings in the brain create electrical activity in the form of pulsations that can be measured by sensors called electrodes. The electrodes are located next to the scalp and connected to the electroencephalograph. By placing the sensors next to the scalp, the machine can record the electric brain pulsation and convert the activity to the peak and gutters. The height of the peak indicates an amplitude, while the distance between the peaks, the frequency.

The beginning of the joke The most active pattern of the brain wool, beta waves indicate vigilance. This electrical activityIt starts at 13 Hz and is probably dominant in reading this page. Higher frequencies in this range (26 Hz and up) are sometimes further defined as gamma waves. Agitated states of emotions, such as fear or anger, create beta waves, as well as tasks that require concentration or create anxiety.

The

alpha waves have a slower frequency of 8-13 Hz, which corresponds to the state of relaxation. You are experiencing alpha status when you allow your mind to drift or float. While watching TV, sitting in the classroom, lecture or even while driving, you can feel "territorial zoning". Meditation can also produce alpha waves and alpha pattern plays an important role in a state of dreams.

Because one falls asleep, the Theta formula prevails at 4-8 Hz. This condition, often full of mental images, was sometimes referred to as "Twilight Sleep". During deeper meditation waves, theta waves can also prevail.

Finally the delta waves pulsateAt only 0.5-4 Hz, which indicates deep sleep without a dream. Delta waves are also a signature of comatose patients. It is interesting to note that children experience the predominance of the waves of delta when they wake up. In adults, this may indicate diseases such as schizophrenia, dementia, intoxication or delirium caused by drug.

In today's stress -conscious world, the state of Alpha paid great attention to his connection with relaxation. Some types of alternative drugs support the deliberately changing brain wave pattern and create a soothing alpha waves. Simple techniques such as eye closure and sit quietly while allowing stress to "drain" from the body, they can result in an increase in alpha waves and a change in mood.

self-therapy involving positive confirmation is generally considered to be more efficient wslepice practiced in the alpha state. Such techniques often include listening to soothing, quiet music or sounds of nature as foreplay for confirmation. Other disciplines focused on growing alpha waves include meditation, yogaand singing. Creative outlets such as painting or gaming tools can also increase the activity of alpha wool.
