title: Environmental complexity does affect scopolamine induced changes in activity.
abstract: Scopolamine increases ambulation and rearing when animals are tested in a simple open field but decreases these responses when they are tested in complex environments. The nature of the testing environment, in particular its complexity, may therefore need to be considered more closely when the effects of psychotropic drugs are being assessed.
