Neurograins (IMAGE) Brown University Caption The international team of engineers, neuroscientists and physicians involved in the project envisions an approach to neural interfaces that is unlike any available today. They aim to create a 'cortical intranet' of tens of thousands of wireless micro-devices -- each about the size of a grain of table salt -- that can be safely implanted onto or into the cerebral cortex, the outer layer of the brain. The implants, dubbed 'neurograins,' will operate independently, interfacing with the brain at the level of a single neuron. The activity of the devices will be coordinated wirelessly by a central communications hub in the form of a thin electronic patch worn on the skin or implanted beneath it.
