Effects of placebo (saline) injections on core temperature in the rat
(Elsevier, 1990)
1. Core temperature was telemetrically measured in 15 rats before (i.e., at baseline) and at 10-min intervals for 120 min following the injection of normal saline (1 ml/kg ip) or "no injection."2. The sample exhibited a ...
Effects of clonidine and some α-adrenergic antagonists alone and in combination on schedule-controlled behavior in pigeons and mice
(Springer-Verlag, 1984-04)
Schedule-controlled responding was maintained under multiple fixed-interval, fixed-ratio schedules in pigeons and single fixed-ratio schedules in mice. In pigeons, clonidine, an α 2 -receptor agonist, produced dose-related ...
Sensitization to systemic amphetamine produces an enhanced locomotor response to a subsequent intra-accumbens amphetamine challenge in rats
(Springer-Verlag, 1991-05)
Repeated amphetamine (AMPH) administration into the nucleus accumbens does not enhance (sensitize) the locomotor activity produced by a subsequent systemic AMPH challenge. We report here, however, that pretreatment with ...
Effects of apomorphine on elicited and operant pecking in pigeons
(Springer-Verlag, 1980-12)
The effects of apomorphine (0.001–32.0 mg/kg) on elicited and operant pecking were studied in pigeons. Elicited pecking was measured in a 1-h observation test. Apomorphine caused dose-related increases in the pecking ...
Psychomotor stimulant effects of beta-phenylethylamine in monkeys treated with MAO-B inhibitors
(Springer-Verlag, 2001-12)
Rationale and objective: Sufficiently high doses of β-phenylethylamine (β-PEA), a trace amine that is rapidly metabolized by monoamine oxidase-type B (MAO-B), can produce effects comparable to those of cocaine or methamphetamine ...
First dose behavioral tolerance to phencyclidine on food-rewarded bar pressing behavior in the rat
(Springer-Verlag, 1980-06)
The behavioral effects of single doses of phencyclidine (PCP) were examined in drug-naive adult male Holtzman rats trained to press a bar on a fixed ratio (4) schedule (FR 4 ), i.e., a reward of sugarsweetened milk was ...
Antalarmin, a putative CRH-RI antagonist, has transient reinforcing effects in rhesus monkeys
(Springer-Verlag, 2002-11)
Abstract
Herbal extracts and memory enhancement: response to Scholey et al.
(Springer-Verlag, 2005-05)
Regional inhibition of sympathetic tone during shivering and induced muscle contraction,
(Elsevier, 1966-07)
Adrenergic vasoconstriction evoked by the stimulation of the decentralized lumbar sympathetic chain can be inhibited during muscle contraction induced by shivering, sciatic nerve stimulation, or activation of the viscero-somatic ...
