EEGsignaaleja

EEGsignaaleja refers to electroencephalography signals, which are recordings of the electrical activity of the brain. These signals are measured using electrodes placed on the scalp. The brain's neurons communicate through electrical impulses, and EEGcap capture these collective electrical fluctuations. The resulting signals are typically displayed as waveforms, representing different brainwave frequencies.

These frequencies are categorized into distinct bands: Delta (slowest, associated with deep sleep), Theta (sleep or deep relaxation), Alpha (relaxed wakefulness), Beta (active thinking and concentration), and Gamma (higher cognitive processing). The amplitude and frequency of these brainwaves can vary significantly depending on a person's state of consciousness, cognitive activity, and neurological condition.

EEGsignaaleja are used in various applications, including diagnosing neurological disorders like epilepsy and sleep disorders, monitoring brain function during surgery, and in research to understand cognitive processes, emotions, and brain-computer interfaces. The interpretation of EEGsignaaleja requires specialized knowledge and experience, as the signals can be complex and influenced by many factors.
