El análisis tradicional del electroencefalograma (EEG) se realiza en el tiempo. Para ello se selecciona una sección del registro donde la contaminación es baja y posteriormente se cuenta el número de picos.

Con el propósito de mejorar el estudio del EEG reduciendo el factor subjetivo, se han aplicado dos técnicas para el análisis espectral. La primera se refiere a la Transformada de Fourier y el periodograma modificado; la segunda ajusta un modelo Autorregisivo (AR) al EEG y con base en este se obtiene un estimador de la densidad espectral. Adicionalmente, los parámetros del AR permiten monitorear la evolución del EEG.
