‘Disfacilitation’ of red nucleus neurones
Experientia, 1965Dans les neurones du noyau rouge, il a ete demontre par l'enregistrement intracellulaire que les potentiels hyperpolarisants de longue duree sont produits par la stimulation de la region du noyau interpose et du cortex cerebelleux. En changeant le potentiel de membrane de la cellule, l'amplitude de l'hyperpolarisation diminue ou augmente parallelement ...

Targeting the Red Nucleus for Cerebellar Tremor
The Cerebellum, 2014Deep brain stimulation of the thalamus (and especially the ventral intermediate nucleus) does not significantly improve a drug-resistant, disabling cerebellar tremor. The dentato-rubro-olivary tract (Guillain-Mollaret triangle, including the red nucleus) is a subcortical loop that is critically involved in tremor genesis.

The reactivation of the red cell nucleus
Journal of Cell Science, 1967ABSTRACT When the nucleus of a mature hen erythrocyte is introduced into the cytoplasm of a HeLa cell it resumes the synthesis of RNA and DNA. This reactivation of the red cell nucleus in the heterokaryon is associated with a marked increase in its volume. There is a direct relationship between the volume of the nucleus and the amount of

Electrical constants of neurons of the red nucleus
Experimental Brain Research, 1975Membrane electrical constants have been studied in neurons of the red nucleus (RN) of the cat which were identified antidromically from the spinal cord. For each cell, the input resistance was determined from the membrane potential changes to current steps and was found to be 2.5+/-0.9 Momega in twenty five RN cells studied.

The mechanism of the regulation of muscle tonus has constituted a long and absorbing, although as yet uncompleted, chapter in the study of functional neurology. Recently, a certain school of investigation, now led by Rademaker, designated the nucleus ruber as the chief center for the regulation of muscle tonus, and in support of this idea, Rademaker 1 ...

An ultrastructural study of the red nucleus in the rat
Journal of Comparative Neurology, 1975AbstractThe red nuclei of 14 adult male rats of the Wistar strain were prepared for electron microscopic study following perfusion with a mixture of aldehydes. Neurons of four size categories were identified in 1 μ Epon sections and their ultrastructural characteristics were studied in adjacent thin sections.

Pharmacological properties of feline red nucleus
International Journal of Neuropharmacology, 1969Abstract Biogenic amines and related compounds, and certain amino acids were applied by microelectrophoresis onto single red nucleus neurons. The cats were either lightly anesthetized or specially prepared in the unanesthetized state. l -Glutamic and dl -homoeysteic acids were potent excitants while gamma-aminobutyric acid was a strong depressant of ...

Synaptic plasticity in the red nucleus and learning
Behavioural Brain Research, 1988Pairing of the stimulus to the cerebral peduncle (CP) with that to the forearm skin leads cats to flex their forearms within a 10-day training period in response to stimulus to CP, which was initially ineffective. Behavioral study and extracellular unit analysis suggested that the cellular mechanism for this conditioning lies at the corticorubral (CR ...

CONNECTIONS OF THE RED NUCLEUS
Archives of Neurology And Psychiatry, 1940Connections of the red nucleus are complex and hard to elucidate in histologic series of the normal human brain. The difficulties arise from a number of natural conditions. The nucleus occupies a central position in the tegmentum, where it is closely surrounded by ascending and descending fiber tracts.

The greatest difficulty of the experimental neurologist is to present the results of his researches so convincingly that not only will they be accepted by those who are favorably disposed, but that it will not be possible for any one not to accept them. This applies particularly to the investigation of function in the cerebellum and red nucleus.
