Molecular heterogeneity of benzodiazepine receptors
Benzodiazepines exhibit reversible, stereospecific high affinity binding to mammalian brain membranes, and the respective binding sites for 3H-flunitrazepam represent pharmacologically and clinically… Expand

  • 1 February 1979
The effect of the neurotransmitter gamma-aminobutyric acid (GABA) on high-affinity binding of benzodiazepines to brain membranes has been investigated. GABA stimulated [3H]diazepam binding by more… Expand

Dopamine D2 receptors in the rat brain: autoradiographic visualization using a high-affinity selective agonist ligand
The non-catechol, selective dopamine D2-agonist compound 3H-205–502 was used to localize dopamine D2 receptors by autoradiography after in vitro labeling of brain sections. The characteristics of the… Expand

Modulation of acetylcholine release from rat striatal slices by the GABA/benzodiazepine receptor complex.
GABA, THIP and muscimol enhance spontaneous and inhibit electrically induced release of tritium labelled compounds from rat striatal slices which have been pre-labelled with 3H-choline. Baclofen is… Expand

Antipsychotic drugs and dopamine-stimulated adenylate cyclase prepared from corpus striatum of rat brain.
Antipsychotic drugs and their clinically impotent congeners were examined as inhibitors of dopamine-sensitive adenylate cyclase (EC 4.6.1.1) in cell-free membrane preparations of the caudate-putamen… Expand

TAURINE UPTAKE IN SYNAPTOSOMAL FRACTIONS OF RAT CEREBRAL CORTEX 1
Abstract— [35S]Taurine was found to be accumulated in synaptosomal fractions of rat cerebral cortex. Kinetic analysis in the range of 1–800 μm‐[35S]taurine revealed at least two different uptake… Expand
