Aversion to sucrose produced by contingent x-irradiation: Temporal and dosage parameters.

Abstract

RATS WERE FAMILIARIZED WITH MILK FOR 5 DAYS. A FEW DAYS LATER, SS DRANK SUCROSE SOLUTION, AND AFTER 3.5-32 HR. WERE EXPOSED TO 50 R. OF X-RAYS. CONTROLS WERE NOT X-IRRADIATED. IRRADIATED CONTROLS ATE CHOW PRIOR TO IRRADIATION. IN A SUBSEQUENT PREFERENCE TEST, THOSE SS IRRADIATED 6.5 HR. OR LESS AFTER SUCROSE CONSUMPTION EXHIBITED AN AVERSION TO SUCROSE RELATIVE TO BOTH TYPE OF CONTROLS. IN A SIMILAR EXPERIMENT, RATS EXPOSED TO 50, 150, OR 250 R. 7 HR. AFTER CONSUMING SUCROSE SOLUTION DEVELOPED GREATER AVERSION TO SUCROSE SOLUTION WITH INCREASING RADIATION DOSE. (15 REF.) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
