I have no eyes and I must see!

Sea urchins do not have eyes, yet appear to be able to see where they are going. One posible answer: they may use the entire surface of their bodies as a compound eye.

The Phantom Compass Syndrome

Hacking the Senses: The brain is far more plastic than we commonly realize. Presenting new 'senses' via the old inputs works extremely well, to the point that long-term volunteers are a little lost without their new abilities to feel magnetic north or absolute orientation. Tasting direction; feeling pictures. Fascinating stuff. In a loosely related article, genetically modified mice are able to see the full color range visible to humans, even though the last natural mouse able to see this way died out a hundred million years ago. Add the new sensors, and the brain reconfigures. [via]

Seeing with Sound

Seeing with sound.
A researcher in the Netherlands has developed a system that converts pictures from a head-mounted camera into highly complex soundscapes, which are then piped to the user via headphones. After only a week of use, a woman who has been blind from birth can tell a CD from a floppy, and discern whether the lights are on or off. Not quite up to either a bat and/or Daredevil standards, but very cool nonetheless.

Cool eyeball science

Cool eyeball science Quick summary of interesting research on the output of the eyeball. 3 really cool things: 1, we know much more about the output of the eyeball now than a few years ago; 2, they've got a neural network doing visual processing like the eye; 3, most of what you see your brain makes up!
