El presente artículo está enfocado a la Adquisición y Visualización en PC de Señales Electroencefalográfcas EEG, constituyéndose en el primer paso para el desarrollo de un sistema Neurofeedback, lo cual es útil en el diagnóstico de ciertos desórdenes sicológicos. El sistema de canales EEG propuesto está conformado por una etapa de adquisición y acondicionamiento de potenciales cerebrales, una etapa de control, dedicada principalmente a la intercomunicación con el PC, y un módulo de visualización, desarrollado bajo un lenguaje de programación gráfca de alto nivel como LabVIEW, ofreciéndole interactividad al sistema y permitiendo el procesamiento digital de los potenciales neurológicos. De la etapa de acondicionamiento se obtuvo una señal EEG confable, la cual fue registrada en forma adecuada por el módulo de visualización.
Abstract: The present article is intended for the Acquisition and Visualization in PC of Electroencephalographs Signals EEG. It constitutes the frst step in the development of a Neurofeedback system, which is useful in studies dedicated to the diagnosis of certain psychology disorders. The proposed EEG channels equipment is composed of a brain potentials acquisition and conditioning stage, a control module, dedicated mainly to the intercommunication with the PC, and a visualization phase, which was developed under a high level programming graphic language as LabVIEW, providing the interactivity with the system and allowing also the digital processing of the neurological potentials. A reliable EEG signal has been obtained from the conditioning stage and displayed in a proper form in the visualization module.
