El estudio científico de la consciencia requiere encontrar disociaciones entre la consciencia y los mecanismos perceptivos no implicados directamente en la formación de la imagen consciente. Una de las mejores disociaciones es la rivalidad binocular. La rivalidad binocular aparece cuando se presentan imágenes dicópticas que no pueden fundirse, lo que resulta en que la consciencia oscila entre los perceptos posibles. De esta forma, la consciencia cambia pero la estimulación permanece constante. El presente artículo revisa los hallazgos con fMRI (resonancia magnética funcional) y microelectrodos que emplearon la rivalidad binocular y se concluye que existe actividad asociada con la consciencia en toda la vía visual ventral.
