Antalarmin, a putative CRH-RI antagonist, has transient reinforcing effects in rhesus monkeys
(Springer-Verlag, 2002-11)
Abstract
Response repetition in pigeons: pharmacological and behavioral specificity
(Springer-Verlag, 1986-12)
Using a reinforcement schedule that arranges random sequences of reinforcements over two response keys, low and high probabilities of repetition of non-reinforced responses were generated in two groups of pigeons ( n =3 ...
2-amino-6-trifluoromethoxy benzothiazole (PK 26124), a proposed antagonist of excitatory amino acid neurotransmission, does not produce phencyclidine-like behavioral effects in pigeons, rats and rhesus monkeys
(Elsevier, 1988-07)
PK 26124, a proposed excitatory amino acid antagonist, was compared to mephenesin and phencyclldine (PCP).In pigeons, PK 26124 and mephenesin produced loss of righting that was to some extent associated with eye closure ...
Local administration of Δ9-tetrahydrocannabinol attenuates capsaicin-induced thermal nociception in rhesus monkeys: a peripheral cannabinoid action
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-04)
Rationale: Cannabinoids can reduce nociceptive responses by acting on peripheral cannabinoid receptors in rodents. Objectives: The study was conducted to evaluate the hypothesis that local administration of Δ 9 ...
Naltrexone reduces ethanol- and sucrose-reinforced responding in rhesus monkeys
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
These experiments evaluated the ability of naltrexone (NTX) to reduce selectively oral and IV ethanol-reinforced responding, and examined the ethanol-NTX interaction in terms of the competitive opioid antagonist property ...
Increased sensitivity of adenylate cyclase activity in the striatum of the rat to calmodulin and GppNHp after chronic treatment with haloperidol
(Elsevier, 1986-06)
Chronic treatment of rats with haloperidol causes behavioral supersensitivity to dopaminergic agonists and an increase in the sensitivity of adenylate cyclase activity in the striatum to stimulation by dopamine. In this ...
Local administration of mu or kappa opioid agonists attenuates capsaicin-induced thermal hyperalgesia via peripheral opioid receptors in rats
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-02)
Rationale : By acting on peripheral opioid receptors, opioid agonists can attenuate nociceptive responses induced by a variety of agents. Objectives : This study was conducted to characterize capsaicin-induced thermal ...
