Deep neural networks uncover what the brain likes to see

Opening the eyes immediately provides a visual perception of the world—and it seems so easy. But the process that starts with photons hitting the retina and ends with 'seeing' is far from simple. The brain's fundamental task in 'seeing' is to reconstruct relevant information about the world from the light that hits the eyes. Because this process is rather complex, nerve cells in the brain—neurons—also react to images in complex ways.
