The synaptic organization of the caudate nucleus

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1971
Abstract The synaptic organization of the caudate nucleus appears to be homogeneous with no specialized groupings of axon terminals and postsynaptic profiles. The nerve terminals in the caudate nucleus fall into two size groups, one about 1 fim in diameter and the other about 5 /itn diameter.

Morphometric Analysis of Neuronal and Glial Cell Pathology in the Caudate Nucleus in Late-Life Depression

American Journal of Geriatric Psychiatry, 2011
Objective: To assess glial and neuronal density and neuronal volume in two areas of the caudate nucleus in late-life major depression. Design: A postmortem study using the disector and nucleator methods to estimate neuronal density and volume and glial ...

The cognitive functions of the caudate nucleus

Progress in Neurobiology, 2008
The basal ganglia as a whole are broadly responsible for sensorimotor coordination, including response selection and initiation. However, it has become increasingly clear that regions of the basal ganglia are functionally delineated along corticostriatal lines, and that a modular conception of the respective functions of various nuclei is useful.

Neuronal distribution in caudate nucleus and reticular-caudate pathways

Brain Research Bulletin, 1978
Methods of quantitative stereology are employed to determine the cell body diameters and the disposition of the neurons of caudate nucleus (CN) of the cat. Large neurons are more frequent in the infero-external region in a well defined zone 16 to 18 mm ahead of the interaural plane.

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.

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.

Effect of the Serotonergic System on the Caudate Nucleus

Pharmacology, 2008
Effects of L-5-hydroxytryptophan (L-5HTP), an active precursor of 5-hydroxytryptamine (5-HT), and electrical stimulation of the dorsal raphe nucleus were observed on the activity of the caudate nucleus in cats with electroencephalographic and evoked potential studies. In an electroencephalographic study, the caudate spindle and the VA spindle, recorded

Stimulation of Caudate Nucleus

Archives of Neurology, 1961
Studies employing electrical stimulation in chronically prepared, freely moving animals have given disappointingly little information about the functions of the caudate nucleus. In those instances in which positive motor responses have been reported, 1,2,7 there is still the problem of refuting or confirming Kinnier Wilson's arguments that the effects ...

Caudate nucleus and memory for egocentric localization

Behavioral and Neural Biology, 1988
A large body of evidence suggests that the caudate nucleus (CN) plays a critical role in the processing of spatial localization information. Furthermore, evidence has begun to accumulate that the CN is involved in the processing of a very specific class of spatial cues, namely, egocentric cues (localization with reference to the organism).
