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 ...
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 ...
The effects of four days of continuous striatal microdialysis on indices of dopamine and serotonin neurotransmission in rats
(Elsevier, 1991-12)
The effects of 4 days of continuous microdialysis with a small-diameter concentric-style probe on indices of striatal dopamine (DA) and serotonin neurotransmission were assessed. It was found that over 4 days of dialysis, ...
Dopamine depletion in neonatal rats: effects on behavior and striatal dopamine release assessed by intracerebral microdialysis during adulthood
(Elsevier, 1990-01-29)
Rats depleted of dopamine (DA) by intraventricular 6-hydroxydopamine (6-OHDA) in infancy show behavioral impairments as adults, but their basic sensory-motor functions and feeding abilities are intact; at least relative ...
The temporal structure of spike trains in the primate basal ganglia: afferent regulation of bursting demonstrated with precentral cerebral cortical ablation
(Elsevier, 1991-03-08)
We studied the temporal pattern of discharge of single units in the basal ganglia of awake primates sitting quietly. Bursting was studied with a procedure that identified individual bursts in a spike train, quantifying ...
Changes in medial cortical blood flow with a stimulus-response compatibility task
(Elsevier, 1994-02)
Previous work has suggested that human subjects engaged in tasks, like the Stroop task, that require response selection utilize the medical frontal cortex. We used positron emission tomography to measure blood flow changes ...
Extrinsic current and flash sensitivity in turtle cones
(Elsevier, 1994-02)
The effects of hyperpolarizing current and background light on intracellular responses of red cones in turtle were compared. Even though a background light always reduced response amplitude, hyperpolarizing current did so ...
The long-term effects of neurotoxic doses of methamphetamine on the extracellular concentration of dopamine measured with microdialysis in striatum
(Elsevier, 1990-03-02)
The extracellular concentrations of dopamine (DA), dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5-HIAA) in the striatum were measured by in vivo microdialysis in freely moving ...
Recovery from lateralized neocortical damage: dissociation between amphetamine-induced asymmetry in behavior and striatal dopamine neurotransmission in vivo
(Elsevier, 1992-02-07)
It has been hypothesized that neocortical damage is accompanied by secondary changes in other brain areas (the shock or diaschisis of von Monakow), which contributes to initial non-specific behavioral depression. The ...
