Webb3 aug. 2024 · There are many types of brain waves that an EEG records. The basic brain waves are alpha, beta, theta, and delta waves. There are other more complex waves. Each type of brain wave has a normal frequency, height, shape, and location. A person’s age can also determine whether a certain brain wave is normal or not. Die makroskopisch sichtbare elektrische Hirnaktivität kann Motive aufweisen, die rhythmischer Aktivität gleichen. Grundsätzlich gleicht das EEG jedoch dem 1/f-Rauschen und enthält keine lang andauernden Oszillationen. Verschiedene Wachheitsgrade werden von Änderungen des Frequenzspektrums der EEG-Signale begleitet, sodass sich durch eine Analyse der gemessenen Sp…
