Synaptic excitation of red nucleus neurones by fibres from interpositus nucleus

Experimental Brain Research, 1970
Electrophysiological properties of the interpositus-rubral transmission were studied in anaesthetized cats. The axons of interpositus neurones were stimulated either at their origin in the interpositus nucleus or at their terminal in the ventrolateral nucleus of the thalamus.

CEREBELLUM AND RED NUCLEUS

Archives of Neurology & Psychiatry, 1934
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.

Red nucleus: role in motor control

Current Opinion in Neurobiology, 1991
Experimental reports in the past year have provided a better understanding of the motor functions of excitatory and inhibitory neurotransmitters in the red nucleus, and of the sensorimotor properties of single rubral neurons. These data fit well within the framework of a neural network model of the rubrocerebellar system.

Eye movement-related neurons in the red nucleus

Neuroscience Letters, 1990
Extracellular unit activity of the parvocellular red nucleus (RN) and spontaneous horizontal eye movements were recorded in adult, nitrous oxide-anesthetized and C1 transected cats. It was found that 7.5% of the neurons of each RN were related to spontaneous horizontal saccadic eye movements.

Red Nucleus Stimulation Inhibits Within the Inferior Olive

Journal of Neurophysiology, 1998
Horn, K. M., T. M. Hamm, and A. R. Gibson. Red nucleus stimulation inhibits within the inferior olive. J. Neurophysiol. 80: 3127–3136, 1998. In the anesthetized cat, electrical stimulation of the magnocellular red nucleus (RNm) inhibits responses of rostral dorsal accessory olive (rDAO) neurons to cutaneous stimulation.

CONNECTIONS OF THE RED NUCLEUS

Archives of Neurology And Psychiatry, 1940
Connections 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.

Electrical constants of neurons of the red nucleus

Experimental Brain Research, 1975
Membrane 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.

Motor cortical modulation of the macaque red nucleus

Experimental Brain Research, 1981
The nuclei of the neocerebellum receive inputs from somatosensory receptors and the motor cortex. In cats, the discharge of those nuclear neurons which were driven by passive movement of a limb segment in one direction was suppressed by stimulation of the cortical site from which movement was evoked in the opposite direction (Larsen and Yumiya 1979a ...

The reactivation of the red cell nucleus

Journal of Cell Science, 1967
ABSTRACT 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

Spinal Projections of the Cat Parvicellular Red Nucleus

Journal of Neurophysiology, 2002
Traditionally, the red nucleus of the cat is divided into two parts: a large-celled, magnocellular, division (RNm) and a small-celled, parvicellular, division (RNp). The RNm projects to the spinal cord and receives input from the cerebellar interpositus nucleus.
