We live in a world where our eyes and ears are almost constantly bombarded with colors, shapes, textures and noises of all types. How exactly do our brains translate these sights and sounds into meaningful images and words? At the University of California, Berkeley, two groups of scientists are finding tantalizing new answers to this question. Their remarkable successes at reconstructing what our brains see and hear offer hope for future life-changing technologies.
