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 ...
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 ...
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 ...
Behavioral sensitization: Characterization of enduring changes in rotational behavior produced by intermittent injections of amphetamine in male and female rats
(Springer-Verlag, 1984-12)
Factors influencing the behavioral sensitization (“reverse tolerance”) produced by intermittent amphetamine (AMPH) injections were studied by quantifying rotational behavior in rats that had a unilateral 6-hydroxydopamine ...
Effect of ethanol and of noise on reaction time in the monkey: Variation with stimulus level
(Springer-Verlag, 1980-06)
To determine whether the latency-increasing effects of ethanol were differential with respect to the intensity of the stimulus that initiated the response, three rhesus monkeys were trained on a behavioral task in which ...
The influence of estrous cycle and intrastriatal estradiol on sensorimotor performance in the female rat
(Elsevier, 1987-05)
The influence of estrous cycle and intrastriatal implants of 17beta-estradiol (17[beta]-estradiol). 17alpha-estradiol (17[alpha]-estradiol) or cholesterol on the number of footfaults made by female rats traversing a narrow ...
Behavioral effects of thebaine in the rhesus monkey
(Elsevier, 1981-06)
Three experiments were conducted with rhesus monkeys to assess some behavioral effects of the opium alkaloid, thebaine, in relation to its dependence liability. The concurrent intramuscular administration of naloxone did ...
