Shaw's Eco-Logic

You might recognize that line from Isaiah, but did the prophet know anything about the phenomenon called "blindsight"?

My latest HND piece details the story of a physician and double stroke victim, whose visual cortex was ruined, although his eyes were not damaged. Researchers have found that signals from his retina are now picked up in another part of his brain, and he can discern facial expressions and navigate through an obstacle course—despite being blind.

This story seems to be the inverse of work done on a girl whose eyes were damaged in an explosion, but when TV images were fed to her visual cortex, could "see" in her brain.

Amazing stuff!
