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 ...

On the inferior olive of the albino rat
Journal of Comparative Neurology, 1970AbstractThe average of neuron counts made in five rat inferior olives was 24,400 neurons per olive, i.e., 48,800 per rat, — 6.8 times fewer than the number of rat cerebellar Purkinje cells. The medial accessory olive was larger, both in terms of volume and cell numbers, than either the dorsal accessory or principal olives.

Transient neurotensin in the human inferior olive during development
Brain Research, 1988A large number of transient neurotensin-immunoreactive nerve terminals are found in the human principal inferior olive of the medulla oblongata during the first year of age and almost completely disappear in the adult. Their neurotensin content is further characterized as neurotensin(1-13) using radioimmunoassay and gel filtration and reaches 582 pmol ...

Vestibular Responses In The Inferior Olive
1987Single cell recordings and anatomic results both indicate the presence of neurons in the inferior olive sensitive to vestibular stimulation. Complex spikes which presumably originate in the inferior olive can be elicited in cerebellar Purkinje cells by caloric (Ferin et al., 1971), electrical (Precht et al., 1976b, 1977), and natural (Ghelarducci et al.

Main Afferent Connections of the Inferior Olive
1980As seen from Sect. 3, a minor division of the olive usually gives off fibers to various cerebellar regions, and all lobes or lobules of the cerebellum receive afferents from more than one olivary subdivision.
