1. We devised a new light/dark transition apparatus, recorded transitions, % time animals spent outside the dark chambers (% time) and locomotor activity, and evaluated this apparatus by testing anxiolytics, non-anxiolytic drugs and putative anxiogenic drugs in mice. 2. Diazepam
Despite the knowledge that gamma-aminobutyric acid(A) modulators can affect learning and memory, their capacity for disrupting each of these complex processes is rarely compared, and often mistakenly assumed to occur with identical potency. For these reasons, the effects of flunitrazepam

A multiple schedule of repeated acquisition and performance of conditional discriminations was used to characterize the effects of two negative allosteric modulators of the gamma-aminobutyric acid (GABAA) receptor (ethyl beta-carboline-3-carboxylate [beta-CCE] and N-methyl-beta-carboline-3-carboxamide [FG-7142]), a hallucinogenic beta-carboline derivative (harmine), a
Pharmacology, biochemistry, and behavior, 44(3), 633-641 (1993-03-01)
The respiratory and behavioral effects of the benzodiazepine receptor (BZR) inverse agonist ethyl-beta-carboline-3-carboxylate (beta-CCE) were determined alone and in combination with buspirone, lorazepam, flumazenil, and SR 95195 in rhesus monkeys. For the respiratory studies, one group of monkeys inhaled either
Benzodiazepine binding to gamma-aminobutyric acid type A (GABA(A)) receptors allosterically modulates GABA binding and increases the currents induced by submaximal GABA concentrations. Benzodiazepines induce conformational changes in the GABA-binding site in the extracellular domain, but it is uncertain whether these
