They would stick an electrode in a rat's brain and, whenever the rat went to a particular corner of its cage, would give it a small shock and note the reaction. One day they unknowingly inserted the probe in the wrong place, and when Olds tested the rat, it kept returning over and over to the corner where it received the shock.
