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 ...
Effects of tobacco smoking on the topographic EEG I
(Elsevier, 1994-09)
1. 1. The EEG and cardiovascular effects of smoking tobacco cigarettes of varying nicotine content were studied in Japanese chronic tobacco smokers.2. 2. Thirteen female and fifteen male adult normal volunteers were recruited ...
Dexamethasone attenuation of the cortisol response to nicotine in smokers
(Springer-Verlag, 1990-06)
The effect of corticosteroids upon the cortisol response to nicotine from smoking was investigated in five heavy smokers. Corticosteroid activity was manipulated by administering dexamethasone, a synthetic glucocortoicoid ...
Differential effects of pentobarbital, ethyl alcohol, and chlorpromazine in modifying reticular facilitation of visually evoked responses in the cat
(Elsevier, 1969-01)
Cortical visually evoked responses (VER) elicited by electrical stimulation of the ipsilateral optic tract were dramatically facilitated by stimulation of the midbrain reticular formation. This facilitation depended on the ...
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), ...
Antagonism of the discriminative effects of ethylketazocine, cyclazocine, and nalorphine in macaques
(Springer-Verlag, 1984-09)
dl -Ethylketazocine (EKC, 0.01 mg/kg) and saline were established as discriminative stimuli for food-maintained responding in macaque monkeys. Thirty consecutive presses on a right or left lever were reinforced with food, ...
Enkephalinase: Selective inhibitors and partial characterization
(Elsevier, 1980)
There are at least two types of enzymes in brain, endopeptidases and aminopeptidases, which metabolize enkephalins. Evidence is presented to suggest that enkephalinase, an endopeptidase cleaving at the Gly-Phe bond, is ...
A sensitive coupled HPLC/RIA technique for separation of endorphins: Multiple forms of B-endorphin in rat pituitary intermediate vs. anterior lobe
(Elsevier, 1981-08)
A technique is described which couples High Performance Liquid Chromatography (HPLC) to radioimmuno assays (RIA), thus achieving high sensitivity with good specificity. This method allows the separation and detection of ...
Escape from dexamethasone suppression: Possible role of an impaired inhibitory opioid mechanism
(Elsevier, 1983)
1. 1. Several lines of evidence indicate that the activity of the hypothalamus-pituitary-adrenal (HPA) axis in depression is disinhibited.2. 2. Escape from dexamethasone suppression, although not limited to is more frequent ...
