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 ...
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" ...
On drinkometers: Problems and an inexpensive photocell solution
(Elsevier, 1971-12)
Electronic contact switches may interfere with measurements of taste discrimination and also the ability to utilize physiological recording or stimulation techniques simultaneously. An inexpensive and simply constructed ...
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, ...
Systemic hormonal and physiological abnormalities in anxiety disorders
(Elsevier, 1988)
Among the studies of systemic hormonal and physiological abnormalities associated with anxiety disorders, the most consistent and extensive findings suggest (a) peripheral adrenergic hyperactivity (including increases in ...
Susceptibility to sensitization. II. The influence of gonadal hormones on enduring changes in brain monoamines and behavior produced by the repeated administration of -amphetamine or restraint stress
(Elsevier, 1988-09-01)
Repeated amphetamine use produces an enduring sensitization of brain dopamine (DA) systems and behavior. Repeated exposure to stress can also produce sensitization, and amphetamine and stress may be interchangeable in this ...
Effects of damage to superior colliculi and pre-tectum on movement discrimination in rhesus monkeys
(Springer-Verlag, 1984-08)
Eight rhesus monkeys (Macaca mulatta) were trained to detect an instantaneous lateral displacement of a small spot of light. The smallest movement for 79% correct performance was then determined. Severing the splenium of ...
Asymmetry in the effects of unilateral 6-OHDA lesions on eating and drinking evoked by hypothalamic stimulation
(Elsevier, 1985-05)
The present experiment investigated the effects of unilateral 6-hydroxydopamine lesions of the caudate nucleus and nucleus accumbens on eating and drinking evoked by electrical stimulation of the lateral hypothalamus (ESLH). ...
Epilepsy, neuropsychological deficits, and EEG lateralization
(Elsevier, 1987)
One hundred eight epileptic patients (59 men, 49 women; 55% partial seizures, 45% generalized) were examined on 45 indices comprising a modified Halstead Neuropsychological Test Battery. Factor analyses identified five ...
