The direct enhancement of positive palatability by chlordiazepoxide is antagonized by Ro 15-1788 and CGS 8216
(Elsevier, 1987-04)
In a pre previous study, it was found that positive, palatability-dependent consummatory reactions in rats to intraorally infused tastes were facilitated by chlordiazepoxide (10 mg/kg). In contrast, the rats' more neutral ...
The effects of footshock stress on regional brain dopamine metabolism and pituitary [beta]-endorphin release in rats previously sensitized to amphetamine
(Elsevier, 1987-07)
The repeated intermittent administration of amphetamine (AMP) produces an enduring enhancement in the response of dopamine (DA) systems in the brain to a subsequent "challenge" with amphetamine. However, former amphetamine ...
Ganglion cell acuity in hooded rats
(Elsevier, 1982)
Previous measurements of retinal ganglion cell acuity in hooded rats have differed significantly from behavioral tests of visual acuity. One possible source of this discrepancy is examined--that light deprivation in early ...
Sensitization to stress: The enduring effects of prior stress on amphetamine-induced rotational behavior
(Elsevier, 1985-09-16)
In rats with a unilateral 6-OHDA lesion of the substantia nigra exposure to footshock or immobilization stress produced a long-lasting enhancement in the rotational behavior evoked by a subsequent injection of amphetamine. ...
Model of students' mathematics enrollment decisions

A signal generator for testing extracellular recording amplifiers and probes
(Elsevier, 1988-10)
A portable signal generator that simulates the amplitude and frequency of neuronal signals for testing extracellular recording amplifiers is described. The signal generator is easy to construct and it is extremely useful ...
Susceptibility to sensitization. I. Sex differences in the enduring effects of chronic -amphetamine treatment on locomotion, stereotyped behavior and brain monoamines
(Elsevier, 1988-09-01)
There are sex differences in a number of behaviors elicited by amphetamine (AMPH). The purpose of the present experiment was to determine if there are also sex differences in the sensitization of the locomotor activity and ...
Unilateral substantia nigra lesions and schedule-induced polydipsia
(Elsevier, 1986)
The present experiment investigated the effects of unilateral 6-hydroxydopamine lesions of the substantia nigra (SN) on schedule-induced polydipsia (SIP). Lesions were made in either the "dominant" or "non-dominant" ...
Comparison of opioid agonists in maintaining responding and in suppressing morphine withdrawal in rhesus monkeys
(Springer-Verlag, 1981-09)
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, ...
Adrenal medulla grafts enhance functional activity of the striatal dopamine system following substantia nigra lesions
(Elsevier, 1988-10-18)
Adrenal medulla grafts in the lateral ventricle reduce the behavioral manifestations of striatal dopamine depletion in an animal model of Parkinson's disease. Using microdialysis in freely moving rats, the present experiments ...
