Novel technique helps explain why bright light keeps us awake

In recent decades, scientists have learned a great deal about how different neurons connect and send signals to each other. But it's been difficult to trace the activity of individual nerve fibers known as axons, some of ...

Prosthetics for retinal stimulation

In a study recently published in Advanced Biomedical Engineering, researchers at Okayama University report a thin photoelectric film which can stimulate degenerated retinal tissues of the eye.

Light based cochlear implant restores hearing in gerbils

A team of researchers with members from a variety of institutions across Germany has developed a new type of cochlear implant—one based on light. In their paper published in the journal Science Translational Medicine, the ...

Scientists use algorithm to peer through opaque brains

Trying to pinpoint signals from individual neurons within a block of brain tissue is like trying to count headlights in thick fog. A new algorithm, developed by researchers based at The Rockefeller University, brings this ...

Artificial retinas—promising leads towards clearer vision

A major therapeutic challenge, the retinal prostheses that have been under development during the past ten years can enable some blind subjects to perceive light signals, but the image thus restored is still far from being ...

Genetics

Watching the luminescent gene switch

Scientists have found a way to simultaneously monitor the switching on and off of circadian "clock" genes and their effects on mouse behaviour in real-time.
