Red nucleus inhibits breathing during hypoxia in neonates

Respiration Physiology, 1997
Conscious, anaesthetized and decerebrate young mammals respond to acute hypoxia with an initial increase in breathing followed by a fall to, or to below, pre-hypoxic levels--the biphasic ventilatory response. The ventilatory rise is due to sustained hypoxic stimulation of the peripheral chemoreceptors. We present evidence from brain stem and peripheral

Vestibular influences on the red nucleus during sleep

Pfl�gers Archiv f�r die Gesamte Physiologie des Menschen und der Tiere, 1967
The integrated activity recorded from the red nucleus in unrestrained, unanaesthetized cats increases phasically during the outbursts of rapid eye movements which are characteristic of the desynchronized phase of sleep. Bilateral destruction of the vestibular complex, particularly when localized to the medial and descending vestibular nuclei, abolishes

Synaptic plasticity in the red nucleus and learning

Behavioural Brain Research, 1988
Pairing 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 ...

Nucleus-anchoring cytoskeleton in chicken red blood cells

Cell Biology International Reports, 1979
Cytoskeleton of chicken erythrocytes was studies studied after extraction of the cells with Triton X-100. In phase contrast microscopy the extracted cells were seen as ghost-like structures with preserved morphology, distinct nucleus and surrounding plasma membrane remnant.

Corticofugal postsynaptic influences on red nucleus neurons

Neurophysiology, 1971
The responses of red nucleus neurons to stimulation of the sensorimotor cortex was studied on nembutal-anesthetized cats. Most of the rubrospinal neurons were identified according to their antidromic activation. Stimulation of the sensorimotor cortex was shown to evoke in the red nucleus neurons monosynaptic excitatory potentials with a latency of 1.85

Development of the Human Parvocellular Red Nucleus

Developmental Neuroscience, 2008
Morphology of the human parvocellular red nucleus (RNp) was investigated in 14 fetuses aged from 12 to 39 weeks of gestation (WG). The brains were processed into celloidin-embedded serial sections. At 12 WG, the anlage of RNp was observed as an ovoid mass of immature neurons clustering into some groups.

Evolution of the red nucleus and rubrospinal tract

Behavioural Brain Research, 1988
A red nucleus, defined by its relative position in the tegmentum mesencephali, its contralateral rubrospinal or rubrobulbar projections and by crossed cerebellar afferents, is found in terrestrial vertebrates and certain rays. A crossed rubrospinal tract occurs in anurans, limbed urodeles and reptiles, birds and mammals, but is apparently absent in ...

Neurochemical significance of the red nucleus.

Bulletin of clinical neurosciences, 1988
This study reviews some of the more prominent reports related to neuromelanin and the physiological significance of the substantia nigra and the red nucleus. The phylogenetic and ontogenetic parallelism between these two structures is considered. The presence of dopachrome in the red nucleus and of neuromelanin in the substantia nigra is discussed.

THE RED NUCLEUS AND ADJACENT CELL GROUPS

Archives of Neurology & Psychiatry, 1930
Experimental work on the brain should be based on an accurate knowledge of form and structure. This should go beyond a mere familiarity with surface form and typical sections and should include a tridimensional conception of the size, shape, form and relations of the nuclei and fiber tracts.
