An inability of [gamma]-acetylenic GABA to block eating evoked by hypothalamic stimulation
(Elsevier, 1980)
Several lines of evidence have implicated the nigrostriatal dopamine system and the neocortex for eating occurring either spontaneously or in response to electrical stimulation of the lateral hypothalamus (ESLH). GABA-ergic ...
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 ...
Taste responsiveness, weight loss, and the ponderostat
(Elsevier, 1973-11)
Rats which lost weight due to exercise showed increased acceptance of good tasting food and increased rejection of bad tasting food. This indicates that energy deficit results in heightened taste responsiveness and suggests ...
Emotional responses toward humans in monkeys with selective frontal lesions
(Elsevier, 1968-03)
Monkeys with lateral or orbital frontal lesions, operated controls with inferotemporal lesions and unoperated controls were tested for aggressive and aversive responses toward humans as judged by three observers. Contrary ...
Impairment in sampling visual stimuli in monkeys with inferotemporal lesions
(Elsevier, 1970-03)
Monkeys with inferotemporal (IT) lesions and their controls, monkeys with partial removal of striate cortex (LS) and unoperated monkeys, were trained to discriminate between two stimulus compounds differing in brightness ...
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 ...
Unilateral striatal lesions in the cat disrupt well-learned motor plans in a GO/NO-GO reaching task
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-03)
We examined the changes in learned and spontaneous motor behavior after a unilateral excitotoxin lesion of the neostriatum. Cats were trained to perform a sensory-cued GO/NO-GO reaching task. Success rate, reaction time, ...
Depression and neuropsychological test peformance in acute spinal cord injury patients: Lack of correlation
(Elsevier, 1990)
Factors which have been causally related to neuropsychological deficits in acute spinal cord injury (SCI) patients include advanced age, limited educational level, acute traumatic brain injury, alcohol and/or substance ...
Strain differences in eating and drinking evoked by electrical stimulation of the hypothalamus
(Elsevier, 1981-03)
Electrical stimulation of the lateral hypothalamus (ESLH) has been shown to produce individual response differences that cannot be attributed to the neuroanatomical locus of the electrode. The purpose of the present ...
Gonadectomy attenuates turning behavior produced by electrical stimulation of the nigrostriatal dopamine system in female but not male rats
(Elsevier, 1981-05-06)
Rotational behavior induced by electrical stimulation of ascending dopamine neurons is used as a behavioral model to investigate gender and hormonal influences on extra-hypothalamic dopamine systems. Steroid hormones ...
