Primary Cultures of Human Caudate Nucleus

Stereotactic and Functional Neurosurgery, 1988
It is possible to grow functional primary dissociated cultures and explants from stereotactic biopsies of human parkinsonian caudate nuclei. Two major classes of cells were identified on morphological grounds. The culture cells appear to be stimulated by an unidentified soluble factor(s) obtained from human fetal neuronal cells in vitro.

Projections of the Caudate Nucleus in Cats and Kittens

Cells Tissues Organs, 1983
Small electrolytic lesions were placed on the head of the caudate nucleus of kittens between 8 and 21 days postnatally and in adult cats. Coronal sections of the whole brain were studied under the light microscope with the Fink and Heimer staining method.

Neuronal Correlates of Obsessions in the Caudate Nucleus

Biological Psychiatry, 2008
Metabolic overactivity of corticosubcortical loops including the caudate nucleus (CN) has been reported in obsessive-compulsive disorder (OCD) using functional imaging techniques. However, direct proof of a modification of neuronal activity within the CN of OCD patients is still lacking.

TYROSINE HYDROXYLASE IN BOVINE CAUDATE NUCLEUS

Journal of Neurochemistry, 1971
AbstractApproximately 80 per cent of tyrosine hydroxylase activity in bovine caudate nucleus was particle‐bound. The rest of the activity was found in the soluble fraction. The enzyme activity in crude tissue preparations was inhibited, probably by the presence of endogenous inhibitors.

Fatigability of caudate nucleus stimulation in cats

Neuropsychologia, 1976
Abstract Fatigability of the caudate nucleus motor response was investigated in freely moving cats equipped with permanently implanted electrodes. Results were as follows: 1. (1) Under continuous stimulation, the caudate response fatigued in 10–20 min.

Metabolic fate of caudate nucleus dopamine

Brain Research, 1972
Abstract The rate of formation of DM in the guinea pig caudate nucleus was estimated from the rate of conversion of radioactive tyrosine to DM and was found to be 32 nmole/g/h. The formation and elimination of HVA and Dopac from caudate was estimated from their accumulation after treatment with probenecid.

Efferent connections of the caudate nucleus in cats

Neurophysiology, 1976
The structural and ultrastructural changes in the frontal cortex and globus pallidus were investigated after local or extensive destructions of the caudate nucleus. Using the Fink-Heimer method few degenerating fibres of medium and small sizes were observed in the frontal cortex following the local destruction of the caudate nucleus with preliminary ...

The projection pattern of the suprageniculate nucleus to the caudate nucleus in cats

Brain Research, 1986
The suprageniculate nucleus of the posterior thalamus is a source of non-intralaminar thalamic nucleus which projects selectively to the medial and intermediate regions of the caudate nucleus in cats.

Caudate Nucleus and Pain Modulation

Physiology, 1992
The caudate nucleus has an antinociceptive function related to the opioid peptidergic activity of the periaqueductal gray. Intracaudate opioid peptides and acetylcholine promote acupuncture analgesia, whereas dopamine antagonises it.

Caudate Nucleus Morphology in Tardive Dyskinesia

British Journal of Psychiatry, 1996
ObjectiveThe objective of this project was to test whether there are differences in the size of the caudate nucleus in schizophrenic in-patients with and without tardive dyskinesia.MethodThe study was cross-sectional in design, examining group differences between institutionalised schizophrenic patients with and without tardive dyskinesia, using non ...
