Incidental use of ecstasy: no evidence for harmful effects on cognitive brain function in a prospective fMRI study.

abstract：:Young adult rats (5 months) were compared with aged (28 months) rats in their ability to learn and perform in a diazepam drug discrimination. Both groups of rats were drug naive at the onset of the experiment. Adult and aged animals learned to discriminate diazepam. In general, the response rates under both drug and v...
