Uses sound to activate visual cortex

(Newser) – Remember the iconic Star Trek visor that allowed a blind engineer to see? A team of scientists in Israel has developed something like a real-life version of the gadget, the Daily Mail reports. The Sensory Substitution Device turns visual information into sound that blind people can interpret after a little training. The noises activate portions of the visual cortex, which are normally dormant in the blind; this allows them to detect shapes and people around them—and even read.

MRI scans revealed that the visual cortices of blind people using the device were working as they would in the brains of sighted people. "The brain is not a sensory machine, although it often looks like one; it is a task machine," notes inventor Amir Amedi of the Hebrew University of Jerusalem. That means the visual cortex can work even without visual information.

reminds me of the devise that used the tongue to "taste" where objects were in the water, when diving in dark or murky conditions. An array of small electrodes applied voltage to different areas of the tounge to allow stuff indeed. Soon there may be a "Geordi-tronic " prosthesis that allows multi-sensory inputs to either augment or replace some senses

There are sighted people that say they can "see" sounds and tastes. Some say they can "taste" colors. I find that so awesome that we ignore those things. Who knows what discoveries are there.
