Donovan’s Brain

Originally Aired: February 7, 1948

Suspense #283, "Donovan's Brain," Dr. Patrick Corey becomes dangerously consumed by his obsessive experiments to keep brain tissue alive outside the body. Working tirelessly in his laboratory, Patrick has successfully sustained a monkey's brain in a jar using a sophisticated circulation system, demonstrating that it can still react and possibly think independently of its host body. His wife Janet and son David, a medical student, grow increasingly alarmed by his fanatical devotion to work that seems to violate the natural order. Dr. Schrott, a colleague, confronts Patrick about the moral implications of his research, arguing that he's attempting to discover things no man should know and profaning life itself by reducing it to mere chemistry.

As Patrick documents his experiments in his case book, beginning with that fateful December 5th entry, he establishes a chilling framework that suggests something terrible lies ahead. The episode opens with Patrick writing what he knows will be his final entry, asking neither forgiveness nor offering explanation beyond the case book itself, hinting that his breakthrough experiment will lead him down a dark and irreversible path that destroys his psychological fiber.
