Normalization of extracellular dopamine in striatum following recovery from a partial unilateral 6-OHDA lesion of the substantia nigra: a microdialysis study in freely moving rats
(Elsevier, 1988-05-31)
It has been hypothesized that striatal dopamine (DA) terminals undergo compensatory changes in response to partial damage of the mesostriatal DA system, which results in higher concentrations of DA in the extracellular ...
Comparison of the effects of superior colliculus and pulvinar lesions on visual search and tachistoscopic pattern discrimination in monkeys
(Springer-Verlag, 1987-12)
In order to investigate whether pulvinar lesions produce behavioral impairments similar to those that follow superior colliculus lesions, monkeys were tested on a visual search task before and after receiving radiofrequency ...
The influence of estrogen on nigrostriatal dopamine activity : Behavioral and neurochemical evidence for both pre- and postsynaptic components
(Elsevier, 1986-01)
The results of 3 experiments examining the influence of estrogen on the nigrostriatal dopamine (DA) system are reported. In two experiments the influence of hormonal manipulations on amphetamine (AMPH)-induced rotational ...
Differential recognition of two cloned Brugia malayi antigens by antibody class
(Elsevier, 1989-07)
The humoral and cellular immune response to filarial parasites is complex. Numerous studies have shown that antibodies to a large number of protein and non-protein antigens may be produced over the course of infection and ...
Response repetition in pigeons: pharmacological and behavioral specificity
(Springer-Verlag, 1986-12)
Using a reinforcement schedule that arranges random sequences of reinforcements over two response keys, low and high probabilities of repetition of non-reinforced responses were generated in two groups of pigeons ( n =3 ...
Lateral hypothalamic stimulation: Stimulus-bound eating and self-deprivation
(Elsevier, 1982-07)
Research was undertaken in an attempt to clarify the relationship between stimulus-bound eating and self-deprivation produced by electrical stimulation of the lateral hypothalamus. It was hypothesized that if these two ...
Benzodiazepine dependence studies in animals: An overview
(Wiley Subscription Services, Inc., A Wiley Company, 1982)
A selective review of benzodiazepine dependence studies in animals is presented, emphasizing areas of drug self-injection, drug discrimination, and physiological dependence. Benzodiazepines as a class, as well as long-acting ...
Partial generalization in pigeons trained to discriminate morphine from saline: Applications of receptor theory
(Wiley Subscription Services, Inc., A Wiley Company, 1989)
In pigeons trained to discriminate 5.6 mg/kg of morphine from saline, cyclazocine, l-N-allyl-normetazocine (l-NANM, l-SKF10,047), and ketamine, but not U50,488, produced partial generalization, i.e., a maximum level of ...
Impairments in orienting to visual stimuli in monkeys following unilateral lesions of the superior sulcal polysensory cortex
(Elsevier, 1986)
Monkeys were tested for head and eye orientation to illuminated lamps in a hemisphere before and after serial, unilateral lesions of the polysensory superior temporal cortex (STS) or control lesions. Following STS lesions ...
Effects of neonatal forebrain noradrenaline depletion on recovery from brain damage: Performance on a spatial navigation task as a function of age of surgery and postsurgical housing
(Elsevier, 1986-11)
The experiments examined the contributions of forebrain noradrenaline and environmental enrichment to recovery of place navigation ability in rats after hemidecortication in infancy or adulthood. Noradrenaline depletion ...
