What do you think about our new web site?

Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

New hope for the blind from neuroscientists?

RATE THIS! +7

Scientists in the Texas Medical Center believe that there may be a way to use mental images to help some of the estimated 39 million people worldwide who are blind.

 

Scientists in the laboratories of Michael Beauchamp, Ph.D., an associate professor of neurobiology and anatomy at the The University of Texas Health Science Center at Houston (UTHealth) Medical School, and Daniel Yoshor, M.D., an associate professor of neurosurgery and neuroscience at Baylor College of Medicine, have discovered a neural mechanism for conscious perception that could use the brain’s image-generating ability.

 

“While much work remains to be done, the possibilities are exciting,” said Beauchamp, the study’s lead author. “If successful, we would in essence bypass eyes that no longer work and stimulate the brain to generate mental images. This type of device is known as a visual prosthetic.”

 

What do you see, when you turn out the light? 

 

 Someone who is blind might wear eyeglasses containing a webcam. The tiny camera would relay information to a computer chip implanted in a person’s visual cortext,` which would activate electrodes.
“With all the remarkable advances in computers and technology in recent years, the time is now ripe to develop a visual prosthetic. A key obstacle to progress right now is our limited understanding of how brain activity leads to visual perception. This new study is a step toward our goal of better understanding visual perception, so we are better able to make a useful visual prosthetic,” said Yoshor, the study’s senior author.

 

The Houston team and others working in the field of neural engineering are focused on repairing disorders of the brain and nervous system.

Dec16 Thanks for the recommendations you have serhad here. One more thing I would like to express is that laptop memory requirements generally go up along with other advancements in the know-how. For instance, if new generations of processor chips are introduced to the market, there is certainly usually an equivalent increase in the dimensions demands of all computer memory in addition to hard drive space. This is because the program operated through these cpus will inevitably surge in power to make new technology. Reply
