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 stress and REM sleep deprivation on the patterns of avoidance learning and brain acetylcholine in the mouse
(Springer-Verlag, 1973-12)
Pure bred DBA/2J mice were subjected to varying degrees of stress and “water tank” REM sleep deprivation using one-animal cages, large platforms and/or poles. Subsequently, the animals were studied for acquisition, short-term ...
Relation of rat brain acetylcholine levels to duration of self-stimulation and escape behavior
(Elsevier, 1975)
Total brain acetylcholine (ACh) was assayed in groups of animals after various periods of operant responding maintained by electrical stimulation of the lateral posterior hypothalamus or of escape behavior induced by ...
Fenfluramine and N-ethyl amphetamine: Comparison of the reinforcing and rate-decreasing actions in the rhesus monkey
(Springer-Verlag, 1975-01)
N-ethyl amphetamine HCl (NEA) and fenfluramine HCl ( meta -trifluoromethyl N-ethyl amphetamine) were evaluated as reinforcers in rhesus monkeys that had been previously trained to press a lever using food presentations and ...
Effects of d -amphetamine, scopolamine, chlordiazepoxide and diphenylhydantoin on self-stimulation behavior and brain acetylcholine
(Springer-Verlag, 1972-03)
The effects of d-amphetamine (0.25–8), scopolamine (0.25–8), chlordiazepoxide (2.5–40), and diphenylhydantoin (25–75), given i.p. or s.c. on a mg/kg basis, were studied on self-stimulation behavior in the male albino rat. ...
Cocaine, d -amphetamine, and pentobarbital effects on responding maintained by food or cocaine in rhesus monkeys
(Springer-Verlag, 1979-09)
The effects of IM injections of cocaine, d -amphetamine, and pentobarbital were studied in rhesus monkeys whose lever-press responding was maintained under a second-order fixed-interval, fixed ratio schedule of reinforcement. ...
Psychotropic drug influences on brain acetylcholine utilization
(Springer-Verlag, 1972-12)
The cholinergic antisynthesis agent HC-3 was given intraventricularly to young male rats 20–30 days old to deplete brain acetylcholine (ACh). The rate of HC-3 induced depletion of ACh was used as an index of ACh utilization. ...
Interactions of partial LSD analogs with behavioral disrupting effects of LSD and DMT in the rat
(Elsevier, 1978-01-01)
Adult male Holtzman rats were trained to barpress on a schedule whereby every fourth press earned a reward of 0.01 ml of sugar-sweetened milk (FR4). After an i.p. injecton of LSD (0.1 mg/kg) or DMT (3.2 or 10 mg/kg) such ...
