About this image

Scanning electron micrograph of an array of microscopic electrodes used to connect with neurons in the brain. Neural interfaces such as this may be used for recording brain signals and interpreting them (such as operating a prosthetic limb) or for passing information to the brain (such as in hearing or sight impairment). This array was created by using an electric spark to selectively vaporise areas of a polished silicon crystal, leaving these electrodes standing. Each of these electrodes is about 0.1 mm thick. The colours in this image come from multiple secondary detectors in the microscope through a system invented by Mr Scharf. David Scharf Photography, Los Angeles, California, U.S.A.
