A microwave-transparent operant chamber for rats

To study the operant behavior of rats in a microwave field, an operant chamber equipped with a response lever, stimulus lights, and a feeder was constructed using polycarbonate and fiber optic material. The chamber was connected to a personal computer located outside of the microwave chamber to program the schedules of reinforcement and to collect data. The operant chamber did not interfere with the microwave field and kept the subject's body parallel to the E-field for maximum absorption.
