The effect of brainstem transection on blood pressure in the dog
(Elsevier, 1969-03-01)
Blood pressure was compared before and after midpontine pretrigeminal brainstem transection in the dog. Statistically significant decreases in blood pressure were observed 1/2, 1, and 1-1/2 hours after brainstem transection. ...
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), ...
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 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 ...
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. ...
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 ...
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) ...
