[Benzodiazepine receptors in the central nervous system of mammals].

The review describes benzodiazepine receptor in CNS of mammalians. There are two types of benzodiazepine receptors--"central" and "peripheral" with different pharmacological properties. Besides, it is possible to consider that "central" benzodiazepine receptors are not homogeneous, and are presented by two populations which fulfil different physiological role.
