Dissociative 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...
متن کاملVariations in nucleus accumbens dopamine associated with individual differences in maternal behavior in the rat.
Lactating rats exhibit stable individual differences in pup licking/grooming. We used in vivo voltammetry to monitor changes in extracellular dopamine (DA) in the nucleus accumbens (n. Acc) shell of lactating rats interacting with pups and found that (1) the DA signal increased significantly with pup licking/grooming; (2) the onset of such increases preceded pup licking/grooming; and (3) the ma...
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 کاملInterpretive monitoring in the caudate nucleus
In a dynamic environment an organism has to constantly adjust ongoing behavior to adapt to a given context. This process requires continuous monitoring of ongoing behavior to provide its meaningful interpretation. The caudate nucleus is known to have a role in behavioral monitoring, but the nature of these signals during dynamic behavior is still unclear. We recorded neuronal activity in the ca...
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...
