Cybernetics

Old World Blues

 * Lobotomites: They are the result of medical experiments performed at Big MT. The Auto-Doc, programmed by Doctor Mobius, removed their brains and replaced them with Tesla coils, their hearts and their spines with cybernetics. The heart and spine are removed due to "complications caused by removing the brain".  This routine was designed to keep all inhabitants of the Big MT inside and therefore secret, as only a brain inside a functioning human body can bypass the radar fence, and to prevent lobotomites from attacking the Think Thank thanks to the pacification field inside the Dome.
 * The Courier becomes a lobotomite once they arrive in Big MT.

Fallout 4

 * Conrad Kellogg: Has several cybernetic implants including a brain augmenter, limb actuator, and pain inhibitor. The Institute describes him as a "cyborg" and "augmented human being" that has greater combat efficiency, enhanced reflexes, and an enhanced life expectancy.
