Inhibition-mediating dopamine receptors and the control of intracranial reward
(Springer-Verlag, 1979-01)
A receptor selective agonist and antagonist of inhibition-mediating dopamine receptors (type II receptors) produced significant and dose-related alterations in bar-pressing for intracranial reward. Receptor inhibition by ...
The effects of chlorpromazine on psychomotor stimulant self-administration in the Rhesus monkey
(Springer-Verlag, 1972-06)
The effects of acute and chronic chlorpromazine treatment on psychomotor stimulant self-administration behavior in the Rhesus monkey were determined. Chlorpromazine treatment significantly increased the frequency of ...
Effect of photic stimulation on acetylcholine release from cat cerebral cortex
(Elsevier, 1972-01)
Cortical release of acetylcholine was assayed using the leech muscle preparation in cats with transected brainstems. Both spontaneous and elicited somatosensory and visual cortical release of acetylcholine were measured, ...
Short-term effects of marijuana smoking on cognitive behavior in experienced male users
(Springer-Verlag, 1973-03)
The effects of smoking marijuana on the ability to use abstract concepts was tested in 12 experienced marijuana users. Each subject was tested three times, after smoking prepared 300 mg cigarettes containing either 0, 1.5 ...
Levels and distribution of central nervous system amines in normal and morphine-dependent monkeys
(Elsevier, 1972-03)
The distribution of norepinephrine, dopamine and 5-hydroxytryptamine in various areas of the CNS of the normal monkey has been presented.The central levels and distribution of norepinephrine, dopamine and 5-hydroxytryptamine ...
Naloxone enhancement of DMT and LSD-25 induced suppression of food-rewarded bar pressing behavior in the rat
(Springer-Verlag, 1979-01)
The narcotic antagonist naloxone was tested to determine its possible interaction with N,N-dimethyltryptamine (DMT) and lysergic acid diethylamide-25 (LSD) in adult male Holtzman rats trained to press a bar on a fixed-ratio ...
GABA involvement in memory consolidation: Evidence from posttrial amino-oxyacetic acid
(Springer-Verlag, 1978-01)
In order to assess the possible effects of central GABA activation on the consolidation of shock avoidance, the GABA-T inhibitor amino-oxyacetic acid (AOAA) was administered posttrial to adult male rats. Learning was ...
The reinforcing property of ethanol in the rhesus monkey
(Springer-Verlag, 1978-01)
Rhesus monkeys received intravenous injections of ethanol during daily sessions contingent on their presses on an available lever. Under the standard conditions, when each response on the lever during a 3-h period each day ...
Effects of morphine, nalorphine and naloxone on neocortical release of acetylcholine in the rat
(Springer-Verlag, 1973-06)
The effects of morphine (10 mg/kg), nalorphine (1 and 10 mg/kg), and naloxone (1 mg/kg) were studied on the neocortical release of acetylcholine (ACh) in midpontine pretrigeminal transected rats. Morphine and, to a lesser ...
Effects of physostigmine on brain acetylcholine content and release
(Elsevier, 1973-01)
The content and release of acetylcholine (ACh) from cat brain and ACh content of rat brain was measured using the frog rectus and leech muscle bioassays before and after physostigmine 100 [mu]g/kgi.v. or i.p. The drug ...
