This is essentially an adaptation of the 1942 novel "Donovan's Brain" by Curt Siodmak. The story was first serialized in three issues of the pulp magazine Black Mask (Sept-Nov 1942) and quickly adapted to radio and motion pictures. The cast of this Outer Limits version features a character named Dr. Hausner, which may be a nod to actor Jerry Hausner who appeared in the first radio version of Donovan's Brain on the series Suspense in 1944.
