Alcohol increases both locomotion and immobility in mice: an ethological analysis of spontaneous motor activity.

abstract：:The performance of healthy volunteer subjects on an auditory latent inhibition (LI) paradigm was assessed following administration of a single oral dose of d-amphetamine or placebo. It was predicted that a low (5 mg), but not a high (10 mg), dose of d-amphetamine would disrupt LI. The prediction was supported with lef...
