A team of researchers affiliated with multiple institutions in Germany has developed a cochlear implant that converts sound waves to light signals instead of electrical signals. In their paper published in the journal Science ...
The key components of electrical connections between light receptors in the eye and the impact of these connections on the early steps of visual signal processing have been identified for the first time, according to research ...
