Inferior Olive: All Ins and Outs

2019
The inferior olive in the ventral medulla oblongata provides climbing fibers to Purkinje cells in the cerebellar cortex as well as collaterals to the cerebellar nuclei and thereby exerts a strong impact on cerebellar output. As a consequence, the intrinsic properties of olivary neurons and the synaptic inputs that modify their output are critical for ...

UNUSUAL RESPONSE OF THE INFERIOR OLIVE TO GLIOMAS

Journal of Neuropathology and Experimental Neurology, 1962
In 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 ...

Inferior Olive of the Cat: Intracellular Recording

Science, 1967
The action potential evoked from inferior olivary neurons of the cat by orthodromic, antidromic, or intracellular stimulation has a large prolonged depolarization, frequently with several superimposed smaller spikes. The all-or-nothing unitary response appears to be a property of the cell, and the later spikes are not secondary to synaptic excitation ...

Pretectal projections to the inferior olive in the rabbit

Experimental Neurology, 1973
Abstract Direct pretectal projections to limited regions of the inferior olivary nucleus were found in the rabbit by means of the Nauta-Gygax and Fink-Heimer methods. The lesions were produced stereotaxically in the pretectal region of five rabbits.

Somatosensory properties of the inferior olive of the cat

Journal of Comparative Neurology, 1983
AbstractWe 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.

Peptide localization in the mouse inferior olive

Journal of Chemical Neuroanatomy, 1997
The inferior olivary complex is the sole source of climbing fibers to the cerebellar cortex. Physiologically these afferents have been shown to have a powerful excitatory effect on their target neurons, namely Purkinje cells. Thus, any modulation of olivary firing rate or responsiveness will alter Purkinje cell firing and ultimately cerebellar function.

On the inferior olive of the albino rat

Journal of Comparative Neurology, 1970
AbstractThe 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.

Hypertrophy of the inferior olives

Zeitschrift f�r Neurologie, 1973
A 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 ...

Inferior olive and oculomotor system

2006
Three subnuclei within the inferior olive are implicated in the control of eye movement; the dorsal cap (DC), the beta-nucleus and the dorsomedial cell column (DMCC). Each of these subnuclei can be further divided into clusters of cells that encode specific parameters of optokinetic and vestibular stimulation.

Yaw direction neurons in the cat inferior olive

Journal of Neurophysiology, 1988
1. Single units that responded to yaw rotation were recorded extracellularly in the caudal inferior olive (IO) of barbiturate-anesthetized cats. Of 276 neurons, 55 responded reliably to yaw, and extensive quantitative data were recorded from 25. 2.
