Enduring changes in brain and behavior produced by chronic amphetamine administration: A review and evaluation of animal models of amphetamine psychosis
(Elsevier, 1986-06)
Some people who repeatedly use stimulant drugs, such as amphetamine (AMPH), develop an AMPH-induced psychosis that is similar to paranoid schizophrenia. There has been, therefore, considerable interest in characterizing ...
PET scan investigations of Huntington's disease: Cerebral metabolic correlates of neurological features and functional decline
(Wiley Subscription Services, Inc., A Wiley Company, 1986-09)
Fifteen drug-free patients with early to midstage Huntington's disease were evaluated with quantitative neurological examinations, scales for functional capacity, computed tomographic (CT) scans, and positron emission ...
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 ...
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 ...
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 ...
Convulsions may alter the specificity of kappa-opiate receptors
(Elsevier, 1986-06)
Morphine, a mu-opiate agonist, and ethylketazocine, a kappa-opiate agonist, produce distinct behavioral, pharmacologic, and biochemical effects. In the mouse, large doses of morphine produce convulsions that are usually ...
