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
Beta-carboline-3-carboxylic acid ethyl ester (beta-CCE; 1.0 or 5.0 mg/kg, i.p.) or vehicle control was administered to male Sprague-Dawley rats immediately after training in an aversively- or appetitively-motivated task. Aversively-motivated training consisted of a one-trial step-though inhibitory (passive) avoidance task with
The effect of CGS 8216 (10 mg/kg) alone and in combination with the imidazodiazepine Ro 15-1788 (10 mg/kg) or ethyl-beta-carboline-3-carboxylate (beta-CCE 1 mg/kg) was tested in the social interaction test of anxiety. All 3 compounds were found to have an
The purposes of the present study were to: (1) characterize the GABAergic input to vasodepressor neurons in the caudal ventrolateral medulla of the cat, and (2) define more precisely the anatomical localization of these neurons in this species. This was

The social interaction test was used to examine the effects of an extract of Ginkgo biloba (EGb 761) and its possible interactions with diazepam and ethyl beta-carboline-3-carboxylate (beta-CCE). Pairs of naive (unfamiliar) male Wistar AF rats subjected to the same
