Some effects of muscarinic cholinergic blocking drugs on behavior and the electrocorticogram
(Springer-Verlag, 1964-03)
Results are presented for the effects of drugs with muscarinic cholinergic blocking actions, both central and peripheral (scopolamine and 1-hyoscyamine) and primarily peripheral (methyl atropine and methyl scopolamine), ...
Hippocampal slow ("arousal") wave activation in the rostral midbrain transected cat
(Elsevier, 1968-11)
The neocortical and hippocampal EEG changes of an acute rostral midbrain cat preparation (brain-stem section at the junction of the diencephalon and midbrain) are described. 1. 1. In the neocortex an alternation of very ...
Effects of physostigmine on rat brain acetylcholine, acetylcholinesterase and conditioned pole jumping,
(Elsevier, 1968-03)
The present study was designed to provide evidence that the behavioral effects of physostigmine are related to inhibition of brain acetylcholinesterase (AChE). Adult male Holtzman rats were trained to pole jump to a buzzer ...
Effects of various drugs on activity of the neuronally isolated cerebral cortex
(Elsevier, 1960-08)
The topical application of strychnine, d-tubocurarine, pentylenetetrazole, picrotoxin, and physostigmine evoked different patterns of electrical activity in a portion of the acutely isolated suprasylvian gyrus of dogs. ...
Effects of psychoactive agents on acquisition of conditioned pole jumping in rats
(Springer-Verlag, 1965-07)
Albino rats required progressively more trials to reach a 90 percent avoidance criterion and achieved less mean total percent avoidance learning than saline injected controls following administration of increasing doses ...
An analysis of the electrical burst phenomenon in some rhinencephalic structures of the dog and monkey
(Elsevier, 1960-08)
Electrical bursts of approximately 20 to 40 c/sec. were observed in some rhinencephalic areas including the olfactory bulb, olfactory stria, pyriform and prepyriform cortex, and the medial amygdala of the dog and the monkey ...
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. ...
