HYPERTROPHY OF THE INFERIOR OLIVES IN THE CAT
Journal of Neuropathology and Experimental Neurology, 1962In this paper 2 cases of olivary neuronal hypertrophy in the cat were described. They developed following ablation of the cerebellum, the central nuclei included. In one, in which one half of the cerebellum only was ablated totally and the other only partially, the most extensive distribution of hypertrophic neurons was contralateral to the total ...

UNUSUAL RESPONSE OF THE INFERIOR OLIVE TO GLIOMAS
Journal of Neuropathology and Experimental Neurology, 1962In 31 of 78 cases of gliomas of the brain stem the lesions involved the olivary nuclei. Eighteen of the lesions were bilateral. In 3 of the cases of bilateral tumors in which the lesions extended partly into the olive from the rostral end of that structure, the gray matter of the olivary nuclei had a diffuse, enlarged and unusual cellular appearance ...

Somatosensory properties of the inferior olive of the cat
Journal of Comparative Neurology, 1983AbstractWe examined the somatosensory properties of 391 neurons in the inferior olive in 20 cats that were anesthetized with barbiturate or decere‐brated. A response consisted of a single spike with a variable number of wavelets followed by a long refractory period.

Hypertrophy of the inferior olives
Zeitschrift f�r Neurologie, 1973A report is given on 29 cases of olivary hypertrophy of different origin with special reference to the quality and topistic distribution of olivary degeneration in relation to the dating and site of the primary lesion. All except one case of hypertrophic degeneration of the inferior olive resulted from injury to the dentato-olivary pathway; 13 were ...

Influence of inferior olive on flexor reflex activity
Experimental Brain Research, 1986In Wistar rats we have studied the effect of inferior olive lesion or activation on the threshold of a flexor reflex elicited by a nociceptive stimulus applied to the hindpaw. When the inferior olive is lesioned by means of 3-acetylpyridine, the threshold value is significantly decreased. A recovery occurs in 3-4 weeks.

MRI findings of inferior olives in palatal myoclonus
Journal of Neurology, 1989Four patients with palatal myoclonus (PM) were studied with magnetic resonance imaging (MRI). Increased signal intensity and bilateral enlargement of the inferior olives were recognized in two patients with bilateral PM, pontine haemorrhage and neuro-Behçet disease, and a similar olivary change on the contralateral side was noted in a case of pontine ...

Inferior Olive: Functional Aspects
1984The inferior olive nucleus is the source of climbing fibers to the cerebellar cortex (Szentagothai and Rajkovits 1959; Batini et al. 1976; Courville and Faraco-Cantin 1978; Montarolo et al. 1980; Campbell and Armstrong 1983). Much work has so far been devoted to understand its functional role in cerebellar operation and in motor control (see Armstrong ...

Phenotype changes of inferior olive neurons following collateral reinnervation
Neuroscience, 1999Inferior olive neurons are able to enlarge or retract their axonic terminal fields in response to changes in the extension of their target domain. Following Purkinje cell loss, the retraction of target-deprived climbing fibres is accompanied by a size reduction in the inferior olive neuron cell bodies.

Inferior Olive And Motor Control
1987In 1824 Fleurens suggested that the cerebellum is important for the coordination of movements, a regulatory function still believed to be a basic attribute of this structure. However, the role that each of the two main afferent inputs to the cerebellar cortex, the mossy and the climbing fibres, plays in cerebellar function is still unclear.

Functional aspects of the inferior olive.
Archives italiennes de biologie, 1982A review is presented of a series of recent experiments aimed at studying the effects of irreversible lesion and of reversible inactivation of the inferior olive. Following a permanent lesion of the inferior olive, no alteration has been found: i) in the morphology of the synapse between Purkinje and Deiters neurones, and ii) in the inhibitory ...
