Cholinergic modulation of single lateral geniculate neurons in the cat
(Elsevier, 1972-03)
The effects of physostigmine, nicotine and scopolamine were studied on the activity of single lateral geniculate neurons in the acute cat. Most of the lateral geniculate neurons selected were P-cells. These increased their ...
Changes in locomotor activity and naloxone-induced jumping in mice produced by WIN 35,197-2 (Ethylketazocine) and morphine
(Springer-Verlag, 1978-01)
Acute i.p. administration of morphine or cocaine produced increase in locomotor activity in Swiss-Webster female mice that were maximal at 32–100 mg/kg for morphine and at 32 mg/kg for cocaine. WIN 35,197-2 produced ...
Effects of N,N-dimethyltryptamine on electrically evoked responses in the cat visual system and modification by neuroleptic agents,
(Elsevier, 1976-09)
The effects of N,N-dimethyltryptamine on electrically evoked potentials in the visual system of the cat and the interaction of selected neuroleptic agents with dimethyltryptamine were studied. Dimethyltryptamine caused a ...
Pargyline-induced increases in sensitivity to the effects of drugs on operant behavior in pigeons
(Springer-Verlag, 1977-01)
Pigeons responded under a multiple fixedinterval 5-min, 30-response fixed-ratio schedule of food reinforcement. Acute pargyline doses between 10.0 and 50.0 mg/kg (i.m.), given immediately prior to the session, decreased ...
Psychomotor stimulant self administration as a function of dosage per injection in the Rhesus monkey
(Springer-Verlag, 1971-09)
The relationships between drug dosage per injection and response rate, and drug dosage per injection and total daily drug intake were ascertained in Rhesus monkeys which self-administered cocaine, pipradrol, methylphenidate ...
The effects of stimulants and depressants on cocaine self-administration behavior in the Rhesus monkey
(Springer-Verlag, 1973-12)
The effects of acute intramuscular pretreatment with several dosages of a variety of centrally acting compounds on intravenous cocaine self-administration behavior were ascertained. Pretreatment with morphine and pentobarbital ...
Cholinergic mechanisms in the cat vestibular system
(Elsevier, 1975-03)
A neuropharmacological study was undertaken in the cat to obtain further evidence of the role of acetylcholine in vestibular function. It was shown that the vestibular nerve contains about half or less the enzymatic activity ...
Central muscle relaxant effects of diazepam
(Elsevier, 1970-09)
Motor depressant effects of diazepam were studied in the intact, decerebrate and high spinal cat. Diazepam (0[middle dot]125-16 mg/kg i.v.) produced a depression of both the patellar and linguomandibular reflexes in the ...
Food- and drug-reinforced responding: Effects of DITA and d -amphetamine
(Springer-Verlag, 1975-01)
Intravenous pretreatment with DITA (0.1–1.0 mg/kg) decreased the rate of food-reinforced lever pressing in rhesus monkeys. Response rate decreases were dose-dependent but showed the development of tolerance. Self-administration ...
Intracranial reward after Lilly 110140 (fluoxetine HCl): Evidence for an inhibitory role for serotonin
(Springer-Verlag, 1977-01)
The 5-hydroxytryptamine (5-HT, serotonin) specific presynaptic reuptake inhibitor Lilly 110140 (fluoxetine hydrochloride) was injected systemically in rats trained to bar-press for rewarding stimulation to the caudal portion ...
