James Olds and Peter Milner (1954) were trying to implant an electrode in a rat's reticular formation when they placed the electrode incorrectly by mistake. Curiously, as if seeking more stimulation, the rat kept returning to the location where it had been stimulated by the misplaced electrode. When they realized that they had actually placed the device in a region of the , Olds and Milner realized they had stumbled upon a reward center.

Hypothalamus

Explanation:

The hypothalamus is a vital and important part of the brain and they can be see as a small region of the brain in which they often plays a crucial role in many important functions of the body as well as the brain which was why the rat kept returning to the location where it had been stimulated by the misplaced electrode due to the fact that the electrode was incorrectly placed by mistake which in turn affected the way the rat functions because the hypothalamus, like the rest of the brain, consists of interconnecting neurons before they eventually realized that they had actually placed the device in a region of the HYPOTHALAMUS.
