A neural colloid, commonly referred to as simply a colloid and sometimes with the portmanteau neuroid, is a human-implantable multielectrode array (MEA) primarily designed to wirelessly read and stimulate neural activity in the brain. The name stems from the method used to administer the electrodes, which involves suspending them in a colloid and injecting them into the body, after which they migrate to different parts of the brain, such as the cerebral cortex.
