- Abstract
Electrodes were implanted into the septal region in one group of rats and into the lateral hypothalamic region in another group. After stabilizing for lever-pressing rates on a variable interval (VI) schedule for brain stimulation, each group was split into two. One group of septal and one group of hypothalamic animals were given the conditioning procedure for a CER whilst they could not obtain brain stimulation, and the other groups were given the conditioning procedure whilst they were lever-pressing for brain stimulation. Manifestation of the CER was tested whilst the animals were bar-pressing for brain stimulation and it was found possible to condition a CER in all of the animals. A second experiment, using one of the hypothalamic groups, showed that the CER was still manifest on a faster VI schedule, the same as that used for the septal animals. A third experiment, using one of the hypothalamic groups, showed that when the group was on a CRF schedule the CER was significantly attenuated even though it was later manifest on a VI schedule. This work indicates that the CER technique using brain stimulation reinforcement should prove useful for, amongst other things, the study of the interaction between motivation and conditioned emotional responses; also that comparisons between different brain loci for CER phenomena should be based on parametric studies of schedule of reinforcement and current intensity, etc.
