Resumen

Los autores desarrollaron un método de medición de la dimensión de caja fractal del movimiento del globo ocular humano. Encontramos una propiedad fractal en los sujetos esquizofrénicos (n = 20) y los controles normales (n = 20). El valor de la dimensión de caja fractal para los pacientes esquizofrénicos difiere de los resultados obtenidos en el grupo de control
