Resumen

La obtención de información por medio de la medición de señales registradas durante diferentes procesos o condiciones fisiológicas del cerebro es importante para poder desarrollar interfaces computacionales que traduzcan las señales eléctricas cerebrales a comandos computacionales de control. Un electroencefalograma (EEG) registra la actividad eléctrica del cerebro en respuesta al recibir diferentes estímulos externos (potenciales por eventos). El análisis de estas señales permite identificar y distinguir estados específicos de la función fisiológica del cerebro. La Dimensión Fractal se ha utilizado como una herramienta para el análisis de formas de ondas biomédicas, en particular se ha utilizado para determinar la medida de la complejidad en series de tiempo generadas por EEG. El presente documento pretende analizar series de tiempo biomédicas obtenidas por EEG a las cuales se obtendrán la FD por medio de los métodos Higuchi, Katz y Multi-resolución de Conteo de Cajas, que muestre la relación entre el método para la obtención de la Dimensión Fractal y la condición fisiológica de la señal basada en Potenciales Cerebrales Relacionados por Eventos
