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 ...
Effects of estrogen agonists on amphetamine-stimulated striatal dopamine release
(John Wiley & Sons, Inc., 1998-08)
Based upon the observation that estrogen acts in the striatum to rapidly modulate dopamine (DA) neural transmission and DA-mediated behaviors, it has been postulated that these effects of estrogen are mediated by a specific, ...
Lesions of the central nucleus of the amygdala I: Effects on taste reactivity, taste aversion learning and sodium appetite
(Elsevier, 1993-12-31)
Bilateral damage to the central nucleus of the amygdala (CeAX) in the rat blunts need-induced NaCl intake and abolishes daily need-free NaCl intake when measured with a two-bottle test. Such a deficit could be the result ...
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 ...
Excitatory and inhibitory amino acid binding sites in human dentate nucleus
(Elsevier, 1991-09-27)
Autoradiography of excitatory and inhibitory amino acid binding sites in human dentate nuclei indicated virtually no binding to N-methyl-d-aspartate (NMDA) or [gamma]-aminobutyric acidB (GABAB) binding sites, and a low ...
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 ...
Ventral hippocampal muscimol disrupts context-specific fear memory retrieval after extinction in rats
(Wiley Subscription Services, Inc., A Wiley Company, 2006-02)
Research aimed at understanding Pavlovian fear memory extinction has yielded considerable insight into the conditions under which fear memories may become inhibited. After extinction, Pavlovian fear memory retrieval is ...
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" ...
