Summary

This completed study gave 22 healthy volunteers a single dose of diazepam, lorazepam, or a placebo, then used brain scans to see how these drugs affect memory and perception. The goal was to understand why lorazepam may impair unconscious memory more than diazepam. The findings could help doctors use these medications more safely.
