The mode of cerebral excitation of red nucleus neurons
Experimental Brain Research, 19681. In anesthetized cats, potential changes were recorded intracellularly from the red nucleus neurons during single shock stimulation of the sensorimotor cortex, internal capsule and cerebral peduncle. 2. These stimulations monosynaptically produced EPSPs with characteristically slow rising time course.

Eye movement-related neurons in the red nucleus
Neuroscience Letters, 1990Extracellular 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.

Neuronal activity of the red nucleus in Parkinson's disease
Movement Disorders, 2008AbstractPrecise placement of the electrodes for stimulation of the subthalamic nucleus (STN) in Parkinson's disease (PD) is crucial for the therapeutic benefit. As a result of the mistargeting and misplacement of the electrodes during surgery in 2 patients with PD, we have characterized the neuronal firing in the red nucleus (RN) and observed the ...

Effect of fastigial stimulation on neuronal activity in the red nucleus
Experimental Neurology, 1971Abstract Discharges from cells recorded with microelectrodes in the red nucleus of anesthetized cats could be increased or decreased by stimulation of contralateral or ipsilateral cerebellar fastigial nucleus. Contralateral stimulation altered the activity in 10% of the cells studied, whereas ipsilateral stimulation altered 22% of the cells ...

Responses of red nucleus neurons to antidromic and synaptic activation
Journal of Neurophysiology, 1975An account is given of the responses of 432 red nucleus (RN) neurons with axons projecting down the spinal cord. Almost half were in an initial series of 18 experiments on anesthetized cats, and the remainder were in a second series of 12 experiments on decerebrate unanesthetized cats. The differences between the two series were of little significance.

Quantitative analysis of the neuronal population of the red nucleus of the cat
The Italian Journal of Neurological Sciences, 1981There is strong evidence in the literature for a correlation between the two parts of the red nucleus, magnocellular and parvocellular, and different functions. Unfortunately in the cat, the species most studied both physiologically and anatomically, there are no morphological criteria distinguishing the two portions.

Nature of the cerebellar influences upon the red nucleus neurones
Experimental Brain Research, 1968Large cells in the red nucleus of cats were impaled with glass microelectrodes. Under light Nembutal anesthesia it was found that stimulation of the cerebellar cortex produced hyperpolarization in their membrane. Unlike the inhibitory postsynaptic potentials, this hyperpolarization decreased when the membrane was depolarized by passage of currents ...

The ultrastructure of red nuclei neurons in the valine-deficient rat
Experimental and Molecular Pathology, 1979Abstract Valine deficiency in the rat produced a neurologic syndrome characterized by motor incoordination and associated with pathological changes in neurons of the red nuclei. Chromatolysis of the neurons of the red nuclei from valine-starved weanling rats was evident in rats fed a valine-free diet 15 days and occurred prior to obvious clinical ...

Neuronal responses to 5-hydroxytryptamine in the red nucleus of rats
Experimental Brain Research, 1995The effects of microiontophoretic 5-hydroxytryptamine (5-HT) on the firing rate of red nucleus (RN) neurons were studied in urethane-anesthetized rats. The background discharge rate of almost all the neurons tested (97%) was modified by 5-HT, and generally increased (89%). Responses were dose dependent.
