Neuronal mechanisms of ketamine-induced anesthesia
(Elsevier, 1968-11)
The sites of action of ketamine (CI-581; 2-(0-chlorophenyl)-2-methylamino cyclohexamine HCl) were determined in the central nervous system using electrophysiological techniques in both acute and chronic cat experiments. ...
Discriminative stimulus effects of a centrally administered, delta-opioid peptide ( d -Pen 2 - d -Pen 5 -enkephalin) in pigeons
(Springer-Verlag, 1996-10)
The present study assessed the discriminative stimulus effects of the delta-opioid agonist [ d -Pen 2 - d -Pen 5 ]enkephalin (DPDPE) in pigeons. Food-restricted pigeons were trained to discriminate between ICV injections ...
Modulation of morphine sensitization in the rat by contextual stimuli
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-08)
Rationale: The repeated administration of addictive drugs, such as amphetamine, cocaine, and morphine, produces a progressive enhancement (sensitization) of their psychomotor activating effects. We have previously shown ...
Behavioral interactions between opiate and antiepileptic drugs in the mouse
(Elsevier, 1981-04)
Morphine and related opioid compounds are known to possess proconvulsant activity based upon both electroencephalographic and behavioral criteria. The present authors previously suggested that opiate-related seizures were ...
Temperature as a dependent variable in the study of cholinergic mechanisms
(Elsevier, 1988)
Dilsaver, Steven C. and Norman F. Alessi: Temperature as a Dependent Variable in the Study of Cholinergic Mechanisms. Prog. Neuro-Psychopharmacol. & Biol. Psychiat. 1988, : 1-32. 1. 1. Change in core temperature over ...
The preferential release of beta-endorphin from the anterior pituitary lobe by Corticotropin Releasing Factor (CRF)
(Elsevier, 1986)
Although a number of investigators have shown that release of ACTH is accompanied by the release of Beta-endorphin ([beta]-End) and Beta-lipotropin ([beta]-LPH), the proportion of the latter two peptides released with ...
Differential effects of systemically administered nor-binaltorphimine (nor-BNI) on κ-opioid agonists in the mouse writhing assay
(Springer-Verlag, 1994-07)
The opioid antagonist effects of systemically administered nor-binaltorphimine (nor-BNI) were evaluated against the kappa agonists CI-977, U69,593, U50,488, ethylketocyclazocine (EKC), Mr2034 and bremazocine, the mu agonist ...
Cholinergic modulation of single lateral geniculate neurons in the cat
(Elsevier, 1972-03)
The effects of physostigmine, nicotine and scopolamine were studied on the activity of single lateral geniculate neurons in the acute cat. Most of the lateral geniculate neurons selected were P-cells. These increased their ...
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 ...
Steady state levels of pro-dynorphin-related end products in the striatum and substantia nigra of the adult rhesus monkey
(Elsevier, 1985)
Analysis of an acid extract of the striatum of the rhesus monkey revealed that the molar ratio of dynorphin A(1-8)-sized material and dynorphin (A(1-17)-sized material is approximately 1:1. In addition, the molar ratios ...
