Types Of Brain Waves

Before explaining what brain waves are, it is important to understand how neural communication occurs. In general terms, the neurons found in the brain connect to each other through a process called synapses, which consists of the transmission of information through chemical substances. This procedure is repeated every time two neurons communicate through their ends.

In this way, the synapse gives rise to brain waves, which consist of electrical impulses that have various intensities Likewise, this fact denotes differences in the speed of information processing, since some brain waves may be faster than others.

Gamma brain waves are electrical impulses that have the highest frequency In general terms, the Gamma brain wave oscillates between 25 and 100 Hz, although its most common frequency is located at 40 Hz.

Gamma waves are associated with the perception of stimuli during states of consciousness, because in these cases the possibility of focusing attention is higher than in other situations. In turn, this type of brain waves allow the processing of information linked to tasks of considerable cognitive demand.

These brain waves are not as intense as Gamma waves. However, its frequency ranges from 12 to 33 Hz intensity. Beta brain waves manifest when carried out high cognitive functioning activities that require specific skills and abilities.

Likewise, a high attentional focus appears here, since a high degree of concentration on the part of the person is necessary. Some examples of this type of activity could be public speaking or giving a speech, among others.

Alpha waves are electrical signals that have an intermediate frequency, with an intensity that ranges between 8 and 13 Hz. Unlike the brain waves that we have previously explained, Alpha waves manifest themselves in states of mental and physical relaxation

For this reason, the main function of this type of brain wave is to give reassurance warnings in certain situations that require it. In this way, Alpha waves can occur, for example, during moments of meditation or during reactive activities.

This type of brain waves have a lower intensity than those mentioned above, with a general range of 3.5 to 7.5 or 8 Hz. Theta waves promote body relaxation and they are responsible for intervening in the moments before falling asleep.

For this reason, the functioning of Theta Waves is vital when it comes to prolonging moments of relaxation throughout life.

Finally, Delta waves are the lowest type of brain waves. These electrical signals have a low frequency, since they oscillate between 1 and 3 Hz, resulting in moments of deep mental and physical relaxation in people.

Delta waves affect many vital functions that are carried out involuntarily, such as the regulation of heart rate, blood pressure, respiratory rhythm or the deep sleep cycle, among others. Therefore, Delta waves can be indirectly related to the decrease in alertness produced by the body in stressful situations.
