Neural network in the brain, consisting of billions of neurons, linked through several millions of synaptic connections, generating awareness or consciousness. This network is active in our sleep. This neural network transmits information, through the generation of potential electric, also called potential variation of action. Consists of a single response, hundreds of thousands of neurons, and creates a wave variation of electric potential. Electrodes on the scalp, collect these electric potential variations, such as the electroencephalogram (EEG).
EEG recording involves several electrodes placed against each other, in a row, in the head. EEG cannot differentiate between mental States such as arousal, sleep, semi conscious and aware State. Awakened State, fast frequency beta waves appear in increases in frequency of EEG Beta wave, with increase of the concentration. Alpha waves are EEG, provided that the person is relaxing. Sleep is characterized wave slow pace (slow wave sleep), followed by waves of low amplitude rapid (Rapid Eye Movement sleep).
However, EEG surface represents only a part of brain activity. Much of the signals generated from the inside to brain structures, are lost or submerged with other signals and noise (electronic disruption), during the recording.
Psychologists, psychiatrists and neurologists use EEG as a reliable diagnostic tool. Researchers use more specific combination of EEG recordings and studies of brain imaging in diagnosis. Potential studies evoked, associated with EEG, indicates activity in specific areas of the brain.
EEG comments training (Neurofeedback) is a recent development for neurological treatment and behavioral as epilepsy disorders and sleep disorders. EEG comments make patient seized understand the relationship between the variation of EEG and following. Learn how to regulate the EEG spikes and thus control effects of seizure. In the disorder of the sleep EEG comments training provides awareness, dream and excitement linked EEG patterns. Later, patients learn to regulate EEG, gradual entry into sleep and arousal patterns.
Formation of EEG feedback is bed wetting in children with success. In addition, provides training to manage attention deficit hyperactive disorder (ADHD). Its efficacy in the treatment of ADHD suggested that Neurofeedback improving the capacity of attention and focus.
Capacity of Neurofeedback in the growing capacity of care is the basis behind its usefulness in improving performance, athletes and business managers. NASA first used formation of EEG feedback, to improve the performance of an astronaut and administer the seizure during space travel.
Neurofeedback has found wide application in sports. In sports such as gymnastics, swimming, shooting, archery and other comments by EEG, improves performance. During training, has the subject understand the linkage between fluctuations in EEG view and its situational stress. Relaxing, the subject is calm and the concentration increases in performance.
Different types of capabilities are required in other sports. Shooters specialized, for example, exhibit, more Alpha power in the left temporal areas, just before firing. The shot is another area for consideration. Archers, to show better performance, with formation of Alpha comments from the left temporal area, with the temporary zone training law. He left the temporal parietal areas of the brain controlling muscle movements, connected with the development and realization of archery, in the right hand.
However, it is not the increase of Alpha activity is a general reference to improve athletic performance. Other sports such as tennis, cricket, etc. require increasing beta activity to increase arousal or vigilance, further increase focus.
Peak performance training (P.P.T.) is a program for the improvement of the performance. Business groups, use P.P.T. for improving personal performance. P.P.T provides items with an understanding of the current levels of performance. Learn how to make the body to achieve performance improvements, submit, and features work together. Comments by EEG can pay more attention, focus, reduce functional errors and increase performance during P.P.T.
