(Springer-Verlag, 1987-02)
Antagonistic actions of the irreversible, μ-selective antagonist β-funaltrexamine (β-FNA) were evaluated in pigeons trained to discriminate among intramuscular injections of morphine (5.6 mg/kg), saline, and naltrexone ...
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 ...

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), ...
Separation of the convulsions and antidepressant-like effects produced by the delta-opioid agonist SNC80 in rats
(Springer-Verlag, 2005-11)
Delta-opioid agonists produce a number of behavioral effects, including convulsions, antinociception, locomotor stimulation, and antidepressant-like effects. The development of these compounds as treatments for depression ...

Sixteen opioid agonists were studied for their capacity both to maintain responding previously reinforced by codeine and to suppress the withdrawal syndrome induced by morphine deprivation in rhesus monkeys. All compounds, ...
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 ...
