Recognizing the frequency of the waveforms is fundamental to interpreting EEG. Frequency describes how many waves there are per second, and is measured in hertz (Hz).There are four main frequencies of the human brain seen on scalp EEG, in increasing order: delta, theta, alpha and beta. WebThe fundamental frequency, or first harmonic frequency, that drives this mode is f 1 = v λ 1 = v 2 L, where the speed of the wave is v = F T μ. Keeping the tension constant and increasing the frequency leads to the second harmonic or the n = 2 mode. This mode is a full wavelength λ 2 = L and the frequency is twice the fundamental frequency: dickey\u0027s tucson az
