Enkephalin-dopamine interactions in behavioral arousal
(Elsevier, 1979)
1. 1. Central injection of a long lasting enkephalin analog (D-Ala2-leuo-enkephalin-amide) produced a syndrome of stereotyped motor activity.2. 2. This activation syndrome was significantly reduced by two dopamine (DA) ...
Effects of chronic and acute treatment of antipsychotic drugs on calmodulin release from rat striatal membranes
(Elsevier, 1980-03)
Chronic treatment of rats with the antipsychotic drugs haloperidol and (+)-butaclamol results in supersensitivity of striatal dopamine (DA) receptors. Striatal membranes of these animals have an increased content of an ...
Possible muscarinic-cholinergic mediation of patterned aggressive reflexes in the cat
(Elsevier, 1981)
1. 1. Adult female outbred cats were prepared with chronic hypothalamic stimulating electrodes and ventricular cannulae.2. 2. Cats were restrained, and patterned aggressive reflexes of elicited head turning, biting, and ...
Behavioral effects of dynorphin -- a novel opioid neuropeptide
(Elsevier, 1980-08)
Adult male Swiss-Webster mice were implanted with permanently indwelling cannulae with tips within the lateral cerebral ventricle. The neuropeptide dynorphin was infused centrally and subjects were tested on a variety ...
Convulsant activity of a non-peptidic δ-opioid receptor agonist is not required for its antidepressant-like effects in Sprague-Dawley rats
(Springer-Verlag, 2002-10)
Abstract
Effects of various psychotomimetic agents on the eeg and acetylcholine release from the cerebral cortex of brainstem transected cats
(Elsevier, 1972-09)
The effects of i.v. administration of [Delta]9 THC, phencyclidine, the pyrrolidyl and piperidyl isomers of Ditran, and LSD-25 were determined on the spontaneous neocortical EEG and release of acetylcholine (ACh) from the ...
Neuroendocrine effects of l -tryptophan and dexamethasone
(Springer-Verlag, 1986-05)
An infusion of l -tryptophan was administered twice to five healthy male volunteers, once after pretreatment with dexamethasone 1 mg the previous evening and once after no dexamethasone. Cortisol, prolactin, and growth ...
Nicotine-induced eeg and behavioral arousal,
(Elsevier, 1965-11)
(-) Nicotine, in doses of 0.005-0.01 mg/kg given intravenously over 1 min, produced transient behavioral arousal and EEG activation in cats with chronic indwelling brain electrodes. The effects of nicotine were evident ...
Behavioral variables affecting the development of amphetamine tolerance
(Springer-Verlag, 1966-01)
The behavioral effects of chronic administration of d-amphetamine in rats at a dosage of 1 mg/kg were studied with baselines involving either food or shock reinforcement. Food reinforcement was assigned according to a fixed ...
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. ...
