An artificial retina that could help restore sight to the blind

For more than a decade, researchers have been working to create artificial digital retinas that can be implanted in the eye to allow the blind to see again. Many challenges stand in the way, but researchers at Stanford University may have found the key to solving one of the most vexing: heat

First of a kind in-vitro 3D neural tissue model

Researchers at the University of Illinois at Urbana-Champaign have successfully used stem cells to engineer living biohybrid nerve tissue to develop 3D models of neural networks with the hopes of gaining a better understanding of how the brain and these networks work.

Three types of cells help the brain tell day from night

Bright light at night interrupts the bodys normal day-night cycles, called circadian rhythms, and can trigger insomnia. In fact, circadian rhythms play a major role in health. Disrupted day-night cycles have even been linked to increased incidence of diseases like cancer, heart disease, obesity, depressive disorders and type 2 diabetes in people who work night shifts. Therefore, understanding how human eyes sense light could lead to "smart" lights that can prevent depression, foster sleep at night, and maintain healthy circadian rhythms.

BRAIN’S ASTROCYTES PLAY STARRING ROLE IN LONG-TERM MEMORY

Star-shaped cells called astrocytes help the brain establish long-lasting memories, Salk researchers have discovered. The new work adds to a growing body of evidence that astrocytes, long considered to be merely supportive cells in the brain, may have more of a leading role.

Tomorrows bionic eyes will have Predator vision

Whether through illness or injury, 36 million people suffer from blindness worldwide, and until just a decade ago those afflicted had little chance of regaining their sight. In 2009, doctors at the University of Manchester implanted the first Argus II bionic eye in a patient. Now, 10 years later, the makers of the Argus II are trialing a more capable artificial-vision system one thats implanted directly into the patients brain.
