RT Journal Article SR Electronic T1 Transfer of a Response to Naive Rats by Injection of Ribonucleic Acid Extracted from Trained Rats JF Science JO Science FD American Association for the Advancement of Science SP 656 OP 657 DO 10.1126/science.149.3684.656 VO 149 IS 3684 A1 Babich, Frank R.

A1 Bubash, Suzanne A1 Jacobson, Ann YR 1965 UL http://science.sciencemag.org/content/149/3684/656.abstract AB Rats were trained in a Skinner box to approach the food cup when a distinct click was sounded. Ribonucleic acid was extracted from the brains of these rats and injected into untrained rats. The untrained rats then manifested a significant tendency (as compared with controls) to approach the food cup when the click, unaccompanied by food, was presented.
