The Part of the Brain That Lets the Blind See Without Seeing

The weird phenomenon of blindsight—in which people take in visual information about objects without actually "seeing" them—has long intrigued scientists, and with good reason. They've watched people navigate obstacle courses and identify colors while being technically blind. This week, in a study in Nature, neuroscientists point to a part of the brain called the lateral geniculate nucleus (LGN) as the neural key that might make blindsight possible.
