Abstract

Female rats selectively bred on saccharin intake were exposed to stress followed by acoustic startle. Researchers hypothesized that high saccharin (HiS) rats would startle less than low saccharin (LoS) rats; additional patterns were predicted to depend on females? biological reaction to the stressor. Rats were subject to 20, 5 second footshocks prior to a 30 trial startle procedure. A select group of the LoS female rats were given a glucose solution between the stress and startle procedures. Results indicate that female rats show no stress effect and no glucose effect; the only significant difference observed was in the rats? line breeding.
