The direct enhancement of positive palatability by chlordiazepoxide is antagonized by Ro 15-1788 and CGS 8216
(Elsevier, 1987-04)
In a pre previous study, it was found that positive, palatability-dependent consummatory reactions in rats to intraorally infused tastes were facilitated by chlordiazepoxide (10 mg/kg). In contrast, the rats' more neutral ...
The effects of footshock stress on regional brain dopamine metabolism and pituitary [beta]-endorphin release in rats previously sensitized to amphetamine
(Elsevier, 1987-07)
The repeated intermittent administration of amphetamine (AMP) produces an enduring enhancement in the response of dopamine (DA) systems in the brain to a subsequent "challenge" with amphetamine. However, former amphetamine ...
Separation of the convulsions and antidepressant-like effects produced by the delta-opioid agonist SNC80 in rats
(Springer-Verlag, 2005-11)
Delta-opioid agonists produce a number of behavioral effects, including convulsions, antinociception, locomotor stimulation, and antidepressant-like effects. The development of these compounds as treatments for depression ...
Comparison of opioid agonists in maintaining responding and in suppressing morphine withdrawal in rhesus monkeys
(Springer-Verlag, 1981-09)
Sixteen opioid agonists were studied for their capacity both to maintain responding previously reinforced by codeine and to suppress the withdrawal syndrome induced by morphine deprivation in rhesus monkeys. All compounds, ...
Systemic hormonal and physiological abnormalities in anxiety disorders
(Elsevier, 1988)
Among the studies of systemic hormonal and physiological abnormalities associated with anxiety disorders, the most consistent and extensive findings suggest (a) peripheral adrenergic hyperactivity (including increases in ...
The reinforcing property of ethanol in the rhesus monkey
(Springer-Verlag, 1978-01)
Rhesus monkeys received intravenous injections of ethanol during daily sessions contingent on their presses on an available lever. Under the standard conditions, when each response on the lever during a 3-h period each day ...
Some thoughts on the relations between animal and human drug-taking
(Elsevier, 1983)
1. 1. Results of studies of drug self-administration have frequently been suggested as indicators of the potential for abuse of these drugs by humans. Historical data (pre 1970), although scant, supported this suggestion ...
Fenfluramine and N-ethyl amphetamine: Comparison of the reinforcing and rate-decreasing actions in the rhesus monkey
(Springer-Verlag, 1975-01)
N-ethyl amphetamine HCl (NEA) and fenfluramine HCl ( meta -trifluoromethyl N-ethyl amphetamine) were evaluated as reinforcers in rhesus monkeys that had been previously trained to press a lever using food presentations and ...
Competitive and uncompetitive N -methyl- d -aspartate antagonist discriminations in pigeons: CGS 19755 and phencyclidine
(Springer-Verlag, 1995-03)
The purpose of the present studies was to examine representative uncompetitive and competitive NMDA antagonists, as well as the glycine/NMDA antagonist, HA 966, in pigeons trained to discriminate either PCP or CGS 19755 ...
