alfaaktiivisuutta

Alfaaktiivisuutta, also known as alpha activity, refers to the electrical activity of the brain that is not synchronized with external stimuli or other brain regions. It is characterized by low amplitude, high frequency oscillations, typically ranging from 8 to 12 Hz. This type of brain activity is often associated with a state of relaxed wakefulness, where the individual is alert but not engaged in active mental processing. Alfaaktiivisuutta is commonly observed during periods of rest, such as when the eyes are closed or during the transition from wakefulness to sleep. It is also known to increase with relaxation techniques, meditation, and certain forms of mental imagery. The presence of alfaaktiivisuutta can be measured using electroencephalography (EEG) and is an important indicator of cognitive function and mental well-being.
