Acute caudate vascular lesions.
BACKGROUND AND PURPOSE We sought to evaluate demographic features, risk factors, clinical profiles, and behavioral abnormalities in patients with caudate lesion, either with infarct or with hemorrhage involving the caudate nucleus. METHODS We studied all patients with acute caudate stroke confirmed by CT or MRI who were admitted to our stroke unit over a 5-year period. A database containing r...
متن کاملWhy do we have a caudate nucleus?
In order to understand the physiological role of the caudate nucleus, we combine here our laboratory data on cats with reports of patients with selective damage to this nucleus. Cats with bilateral removal of the caudate nuclei showed a stereotyped behavior consisting of persistently approaching and then following a person, another cat, or any object, and attempting to contact the target. Simul...
متن کاملMetabolic Recovery in Caudate Nucleus
I n 3 children who had undergone cerebral hemispherectomy (hemidecortication) between the ages of 1 year 5 months and 4 years for the alleviation of intractable epilepsy, cerebral glucose utilization was studied serially with positron emission tomography. Three to 7 months after hemispherectomy, glucose utilization i n the caudate nuclei on the side of hemispherectomy had decreased to below pre...
متن کاملPredominance of caudate nucleus lesions in acute ischaemic stroke patients with impairment in language and speech
BACKGROUND AND PURPOSE Whereas traditional views of language processing in the brain have assumed that the language function is concentrated to a limited number of cortical areas (Broca's and Wernicke's areas), current knowledge points at a much more complex system of language and speech processing involving many brain areas, both cortical and subcortical. The purpose of the current study was t...
متن کاملDissociative effects of selective lesions in the caudate nucleus of cats and rats.
Lesions in the neostriatal region connected to the prefrontal cortex severely impaired delayed alternation in both cats and rats, whereas no such effect was found after damage to other neostriatal regions. These results indicate that the processes mediating delayed alternation are well localized in the neostriatum of both cats and rats. Two possible models of neostriatal functioning are discuss...
