A SIMPLE TECHNIQUE FOR DELIVERING LIQUIDS DIRECTLY TO THE MOUTH OF AN UNRESTRAINED RAT1
This work was supported by NIMH grant MH08799.
Abstract
A simple surgical procedure is described that makes it possible to deliver liquids directly into the mouth of a freely mobile rat. Data presented show that an 8% sucrose solution delivered by this technique is an effective reinforcer in a variety of simple and discriminative schedules of reinforcement.
