Induction of seizures by stimulation of the caudate nucleus
Electroencephalography and Clinical Neurophysiology, 1962Abstract 1. 1. After injection of eserine into the caudate nucleus, the spindle previously evoked by caudate stimulation disappeared and later electroconvulsive seizures appeared and spread throughout the brain. 2. 2. This seizure activity was prevented by the making of lesions unilaterally in the cortex and rostral extralaminar thalamus and ...

The fine structure of the caudate nucleus of the cat
Journal of Comparative Neurology, 1968AbstractThe fine structure of the caudate nucleus was studied by electron microscopy. Examination of various regions revealed (1) the majority of neurons are small (10–15 μ ) and can be distinguished from larger neurons by the absence of Nissl bodies, (2) synapses occur most often on dendritic spines, and (3) myelinated fibers in the neuropil have a ...

The subcellular fractionation of the bovine caudate nucleus
Neurochemical Research, 1982Two synaptosomal fractions could be obtained from bovine caudate nucleus on sucrose density gradients one of which had a much greater capacity for 'high affinity' choline uptake than the other but comparable amounts of CAT and choline kinase activity.

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 ...

Caudate Nucleus Lesions and Rearing Responses
Psychological Reports, 1975Lesioned rats were observed for 10-min. in a wooden enclosure. Frequencies of rearing were greatest for unoperated, frontal lesioned, and least for those with caudate lesions. Increased arousal of rats with caudate lesions was suspected.

Dopamine receptors in canine caudate nucleus
Molecular and Cellular Biochemistry, 1982Physiological, pharmacological, histochemical and biochemical studies indicate that dopamine receptors are heterogenous in the central nervous system with each individual functions. This review describes pharmacological and biochemical characteristics of dopamine receptors, particularly in canine caudate nucleus, which have been studied in our ...

Effect of the Serotonergic System on the Caudate Nucleus
Pharmacology, 1980Effects 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.

Cognitive operations in the human caudate nucleus
Neuroscience Letters, 1997We have addressed the role of the head of caudate nucleus in taks of lexical decision, semantic categorization, reading aloud, memory retrieval and object naming by recording neuronal activity from depth electrodes in parkinsonism patients. The firing rate of cells was increased within 400-600 ms when semantic processing was required.

Caudate Nucleus and Electrocortical Activation in Cats
Acta Physiologica Scandinavica, 1961AbstractA 14‐lead electrode was used to search for areas in and around the caudate nucleus from which electrocortical arousal could be elicited. Electrocortical arousal was induced from the reticular nucleus of the thalamus and the internal capsule and, probably by current spread, from the fringe of caudate tissue adjacent to the thalamus, but not from

Caudate nucleus and memory for egocentric localization
Behavioral and Neural Biology, 1988A 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).
