Nerve-on-a-chip platform makes neuroprosthetics more effective

EPFL scientists have developed a miniaturized electronic platform for the stimulation and recording of peripheral nerve fibers on a chip. By modulating and rapidly recording nerve activity with a high signal-to-noise ratio, ...

Researcher creates neurons that light up as they fire

In a scientific first that potentially could shed new light on how signals travel in the brain, how learning alters neural pathways, and might lead to speedier drug development, scientists at Harvard have created genetically-altered ...
