Cybernetic brains are where the ego (or controlling AI) resides in synthmorphs and pods. Modeled on biological brains, cyberbrains have a holistic architecture and serve as the command node and central processing point for sensory input and decision-making. Only one ego or AI may "inhabit" a cyberbrain at a time; to accommodate extras, mesh inserts or a ghost-rider module must be used. Since cyberbrains store memories digitally, they have the equivalent of mnemonic augmentation. They also have a built-in puppet sock so that they may be remote-controlled, though this option may be removed by those who value their security. Cyberbrains are vulnerable to brainhacking and other forms of electronic infiltration/attack. Cyberbrains come equipped with two or more pairs of external access jacks, usually located at the base of the skull, which allow for direct wired connections.
