Abstract
The responses to tests of auditory lateralization and temporal order to the administrationw4 of desmethyldiazepam (DMDZ) and of chlorodesmethyldiazepam (Cl-DMDZ) have been investigated. Therapeutic doses of these two benzodiazepines were used. We have tested four groups of 10 healthy normally hearing subjects. It was demonstrated that both DMDZ and Cl-DMDZ cause a temporary disturbance in the lateralization tests: Ai but especially At. The temporal order test is not altered after drug administration. The physio-pathological and topodiagnostic value of these tests and the site of action of the benzodiazepines are discussed.
