Aivoaaltoliike

Aivoaaltoliike, which translates to "brainwave movement" in Finnish, refers to the rhythmic electrical activity of the brain. This activity can be measured using an electroencephalogram (EEG). Different states of consciousness and cognitive processes are associated with distinct patterns of brainwave frequencies. These frequencies are typically categorized into several bands: Delta, Theta, Alpha, Beta, and Gamma.

Delta waves are the slowest and highest amplitude brainwaves, typically observed during deep, dreamless sleep. Theta waves are associated with drowsiness, light sleep, and REM sleep, as well as states of deep relaxation and meditation. Alpha waves are prominent when a person is awake and relaxed, but not actively engaged in intense thought, often seen during quiet contemplation or eye closure. Beta waves are characteristic of normal waking consciousness, alertness, concentration, and active thinking. Gamma waves are the fastest and are thought to be involved in higher cognitive functions, such as learning, memory, and complex problem-solving.

The study of aivoaaltoliike has provided insights into various neurological conditions and the functioning of the brain. Research in this area continues to explore the precise roles of different brainwave frequencies and their potential applications in understanding and treating brain disorders. Changes in brainwave patterns can indicate underlying issues, making EEG a valuable diagnostic tool.
