Although copper sulfate is an emetic stimulus, preliminary experiments failed to obtain a taste aversion in intact rats following intragastric administration as had been previously reported in the literature. Several experiments were therefore run to further investigate the capacity of intragastric copper sulfate to function as an unconditioned stimulus for taste aversion learning and the role of the vagus in mediating that learning. The results of the first series of experiments showed that intragastric administration of copper sulfate (5 mg/kg X 5H2O) was more effective in reliably producing a taste aversion in vagotomized rats than in sham-operated control rats. The second experiment examined the effects of area postrema lesions on the acquisition of a taste aversion produced by intragastrically administered copper sulfate in vagotomized rats. The results indicated that the taste aversion observed following treatment with intragastric copper sulfate in vagotomized rats could be prevented by lesions of the area postrema. The present results indicate that intragastric administration of copper sulfate is a more reliable unconditioned stimulus for taste aversion learning in vagotomized rats than in intact rats. It is not certain what factors might account for the discrepant results between the present experiments and previously published research.
