The effects of scopolamine hydrobromide on one-way and two-way avoidance learning in rats
(Elsevier, 1968-09)
Previous studies have shown certain striking similarities between the behavioral effects produced by some anticholinergic drugs and the effects produced by hippocampal destruction. To investigate this parallel more thoroughly, ...
Species differences in the eeg response to epinephrine, 5-hydroxytryptamine and nicotine in brainstem transected animals,
(Elsevier, 1963-06)
Species differences have been observed in the EEG activation response to intravenous epinephrine, 5-hydroxytryptamine, and nicotine in rabbits, cats, dogs and monkeys. It was also found that a relatively high level of ...
Effects of meprobamate, chlordiazepoxide, diazepam, and sodium pentobarbital on visually evoked responses in the tectotegmental area of the rat
(Elsevier, 1968-05)
The effects of meprobamate, chlordiazepoxide, diazepam and sodium pentobarbital on sensory input to the boundary area between the dorsal midbrain tegmentum and ventral tectum of the rat have been investigated in order to ...
Effects of route of administration on the chronic toxicity of reserpine
(Springer-Verlag, 1967-01)
Cholinergic agonist-antagonist interactions on neocortical and limbic EEG activation
(Elsevier, 1967-09)
The effects of various cholinergic agonists and antagonists and their interactions were determined on the awake-sleep cycle of cats with chronic indwelling brain electrodes. The effects were measured by the use of the EEG ...
Effects of chlorpromazine on some motor reflexes,
(Elsevier, 1963-08)
The effects of chlorpromazine (CPZ) on the patellar reflex and segmentally evoked spinal cord potentials were determined in various cat preparations. CPZ in doses of 1-8 mg/kg given intravenously (as an accumulative dose) ...
Action of nicotine on the ascending reticular activating system
(Elsevier, 1962-12)
Synchronization of the electroencephalogram was produced by midpontine brainstem transection in the rabbit, cat and dog, and by high pontine transection in the monkey. After transection, i.v. injections of 10-20 [mu]g/kg ...
Observations on intraventricular hemicholinium-3-induced eeg seizures,
(Elsevier, 1967-07)
It was observed that intraventricular (i.vt.) injection of HC-3 produced markedly different effects upon the EEG of the dog, dependent upon dose. The high dose (5 mg) investigated in this paper produced seizures with a 20 ...
Effects of morphine and nalorphine upon tooth pulp thresholds of dogs in the alert and drowsy state
(Springer-Verlag, 1960-09)
The alteration of tooth pulp thresholds of dogs with chronically implanted electrodes was determined in the awake and drowsy states after morphine and nalorphine. The elevation in tooth pulp threshold was significantly ...
Morphine self-administration, food-reinforced, and avoidance behaviors in rhesus monkeys
(Springer-Verlag, 1964-03)
1. A fixed interval-fixed ratio chain of behavior was maintained for periods as long as 6 months by intravenously administered morphine.
