New device allows woman to see, even without eyes (recent local TV report)
Futuristic System Brings Vision To Blind (2002, ScienceDaily)
The visual quality seems rather low, but it's still a promising approach. A glasses-mounted camera transmits data to visual processing hardware, which is plugged into electrodes at the back or side of the skull stimulating the surface of the visual cortex. The user sees patterns of dots of light in the visual field - not exactly high-resolution stimulation, but vision is vision.
This is the same project that in 2002 enabled a formerly blind user to drive a car (slowly) around a parking lot.
Artificial vision is one of the most compelling objectives of neuroelectronics research. Not only will an adequate solution require a good physiological understanding of the visual cortex, but it will also require (or generate) a relatively sophisticated understanding of how the brain processes visual information.
On top of that, the method has some significant aesthetic advantages for the user. Just take a look at the picture.

- Computational Vision
The new study A Feedforward Architecture Accounts for Rapid Categorization, Serre, T., A. Oliva and T. Poggio, PNAS 2007, in press [not online yet] reveals the success of a computational version of vision modeled on the visual cortex processes of immediate...
- "the Brain Is The Wildcard"
An eye prosthesis implant has gained FDA approval for clinical trials aiming to restore vision to people blinded by retinal degenerative diseases. Second Sight produced a 16-electrode implant device a few years ago, which five patients are still using...
- The Brain Invigorated By Light
Twenty minutes of bright white light delays sleepiness, and sends a stimulating wave through the brain, enhancing neural activity even during tasks that have nothing to do with vision. Gilles Vandewalle and colleagues used an optic fibre to shine bright...
- Sound Aids Visual Learning
The use of sound during visual training can enhance later performance on a purely visual task, a finding that demonstrates just how much multisensory interaction occurs in brain areas that before now were thought to be dedicated solely to vision. Aaron...
- About Vision Therapy, Ii
I get so many hits on my blog for vision therapy, mostly looking for material about Stereo Sue, so I take it for granted that all of my visitors know what vision therapy is. Bad librarian! It's hard to find a good definition online of vision therapy...
