With this announcement, the FDA proclaimed that much more needs to be known about the initiation, continuation, and discontinuation of these widely-used drugs. Unfortunately, relevant information is lacking, since for many years, there has been a notable sparsity in the funding and conduct of basic and clinical research on these drugs. In order to begin to fill the void, it is valuable to (re)examine animal models. We here describe a model of conditioned place-preference (CPP) for rats and for the first time, to our knowledge, show that the representative benzodiazepine alprazolam induces positive place-preference in male rats.展开更多
