These investigators trained rats to respond to a sound, when a food pellet was awarded. The rat learned that a little click from the feeding machine meant that he was about to receive a choice 45-mg morsel in the form of a food pellet.

After training the rats to respond to the sound, the animals were sacrificed and the brains quickly removed. The RNA was extracted and chemically purified. Samples of this RNA were then injected into control "naive" rats, which had not been trained. These animals were then compared with relatives who had
