A hybrid retinal implant using stem-cell-derived neurons and microelectrodes lowers activation thresholds and improves signal precision, offering a more natural interface for high-resolution vision ...

Implanted microelectrodes used for side-effect-free pain relief By Ben Coxworth October 14, 2021 First author Matilde Forni with a batch of the microelectrodes during the production process – they ...

Electronic devices that can be attached to the skin or even implanted in the body will become more and more prevalent in near-future technology. Such "implantable bioelectronics" are envisaged as ...

The brain is one of our most delicate organs. It’s not really meant to be prodded and poked, hence the nice protective skull surrounding it. That fragility makes experimental devices that use tiny ...

Scientists have examined the use of carbon fiber microelectrodes (CFM) in neurochemical measurements, with an emphasis on the most recent findings and technological advances. In a new article in ...

While still in its infancy and primitive, even crude, two grids of 16 microelectrodes implanted atop the brain of a volunteer with severe epileptic seizures are somewhat successfully decoding brain ...

Brain–computer interfaces are technologies that enable direct communication between brain activity and external devices, enabling researchers to monitor and interpret brain signals in real time. These ...
