Restiform Body

In the present study, labeled fibers from the sacculus, of fine caliber, were found close to the restiform body, both medially and laterally, some even penetrating through this structure.  

The JAFF is surrounded by the CN, flocculus, lateral cerebellar nucleus, lateral vestibular nucleus, and restiform body.  

restiform body (inferior cerebellar peduncle) preparations were obtained from rabbit brain stem slices and homogenized. The neuronal component of the GABA uptake might be due to the adjacent cochlear nuclei coming along in the preparations, whereas the glial component probably belongs to the restiform body proper. Another possibility is that actually both components are due to the myelinated fibers and glia which make up the restiform body..  

The effects of stimulation of the lateral reticular nucleus (LRN) and the inferior cerebellar peduncle (restiform body, RB), as well as the thirteenth thoracic (Th13) and sacral (S1/S2) segments of the spinal cord were tested in 93 cells.  

Antidromic action potentials were recorded following stimulation of the contralateral restiform body (coRB), contralateral gigantocellular nucleus (coGRN) as well as ipsi- and contralateral lateral funiculus of the 13th thoracic segment (iTh13 and coTh13).  

Ascending projections of the cervical spinal cord neurones to the lateral reticular nucleus (LRN) and the restiform body (RB) were electrophysiologically investigated in alpha-chloralose anaesthetized cats.  

Anterogradely labeled axons that originated from the L6-caudal segments ascended contralaterally through the superficial layer of the lateral cord and entered the cerebellum through the superior cerebellar peduncle and the restiform body.  

Recordings of antidromic action potentials from cells in S1 and S2 segments were taken following stimulation of the contralateral gigantocellular nucleus, contralateral restiform body and ipsi- and contralateral grey matter of the C6 spinal segment.  

Its axons cross in the spinal cord, and while in the contralateral restiform body give off collaterals to the vestibular nuclei.  

CCN neurons were identified by antidromic stimulation with electrodes placed in or near the contralateral restiform body.  

For control purposes some stimulating points were placed in the external cuneate nucleus and restiform body.  

Its efferents project along the midline, then pass laterally to follow the ventral external arcuate fibers around the surface of the medulla into the restiform body.  

Labeled axons were traced and reconstructed from the principal olive and dorsal and medial accessory olive up to the entrance of the contralateral restiform body.  

The cochlear nuclear complex was displaced medial to the restiform body in all species; this has previously been reported in other marsupials.  

Antidromic stimulation with an electrode in the restiform body or with several electrodes in the dorsal half of the white matter of the upper cervical cord was used to identify neurons projecting to the cerebellum and spinal cord, respectively. Many neurons were inhibited by stimulation of the restiform body.  

In the S2 segment 77 neurons with axons in the opposite dorsolateral funiculus were recorded; 36 of them were invaded from only the thoracic level, 21 from both the thoracic level and the restiform body, 3 from both the thoracic level and the thalamus, and 17 from both the thoracic level, the restiform body and the thalamus on the contralateral side.  

Type A neurons were activated mostly from the red nucleus (48/86) or the restiform body (24/86). These neurons were activated from the red nucleus (18/30), oculomotor complex (6/30) and restiform body (6/30).  

The fiber course of the spinocerebellar tracts in the ventral and lateral funiculi of the cat spinal cord were studied by a new approach, making cordotomies at different spinal levels or lesions of the restiform body followed by injections of HRP or WGA-HRP into the anterior cerebellar lobe. The tract is topically arranged and passes through the restiform body. A minor portion originating from the sacrococcygeal region enters via the restiform body. These fibers form two groups, one passing through the restiform body, the other through the superior cerebellar peduncle.  

Type II neurons were located in both fastigial and dentate nuclei and were activated antidromically from the restiform body, the medial longitudinal fasciculus close to the oculomotor complex, the red nucleus and the pontine nuclei.  

Computerized tomography showed an intensely enhancing hyperdense mass in the left restiform body.  

Field potentials induced in deep cerebellar nuclei by the electrical stimulation of contralateral red, pontine and reticularis tegmenti pontis oralis nuclei, the restiform body and the inferior olive were recorded in the alert cat. Recording sites in interpositus and fastigial nuclei were selected with the aid of antidromic field potentials induced by red nucleus and restiform body stimulation, respectively.  

Since this group has some similarities to the mammalian group x (location medial to the restiform body, spinal afferents, efferents to the cerebellum), this name was adopted for the pigeon.  

The patient's clinical course and the histopathologic findings of the brain stem involved the vestibular nuclei, facial nerve, nuclei of nerve V, restiform body and middle cerebellar peduncle and labyrinth including loss of sensory epithelium of the cochlea and vestibular system and the ganglion cells of Scarpa's ganglion.  

Reaching the cerebellum via the restiform body, the labelled olivocerebellar axons entered the deep cerebellar white matter anterior to the cerebellar nuclei.  

This pattern of migration could indicate that a few neurons of the deep nuclei remain ectopic, wedged between the restiform body and the BC while receiving an appropriate Purkinje cell (PC) projection..  

Travelling close to the restiform body, the axons terminated at cells lying between the dorsal and posteroventral cochlear nucleus.  

Phosphate-activated glutaminase-immunoreactive granular deposits were densely seen in the brachium pontis and restiform body, suggesting the immunolabeling of mossy fibers of passage.  

Among the newly discovered spinocerebellar cell groups, those at lumbar and more caudal levels of the cat's spinal cord were studied with regard to which of the two cerebellar peduncles, the restiform body or the superior cerebellar peduncle, is used by their axons. Bilateral injections with horseradish peroxidase were made into either of the anterior lobe or the posterior cerebellar termination area for spinocerebellar fibers, following unilateral transections of either the superior cerebellar peduncle or the restiform body, combined with low contralateral transections of the lateral and ventral funiculi. All these neurons were regarded as sending their axons through the restiform body. Following transection of the restiform body, labeled neurons were found in the following areas contralateral to the transection: the dorsolateral nucleus of the L 3-L 6 segments, the lateral part of lamina VII at L 3-L 5/6, the medial part of lamina VII in L 6 and more caudal segments, and the ventrolateral nucleus of L 4-L 5.  

The basal ganglia-induced effects were abolished upon section of the brachium pontis but not of the restiform body.  

Nucleus y was found to be a compact group of cells in a small fiber-free region dorsal to the restiform body.  

FN-induced increases in heart rate, blood pressure, and contractility were reduced or abolished by lesions made in the restiform body or the A5 area, which is homologous to the catecholamine-containing region in cats and rats.  

Some features different from those of Eutheria include the disposition of the cochlear nuclear complex medial to the restiform body, a lack of large spherical cells in the anteroventral cochlear nucleus, a small medial superior olive, and a large superior paraolivary nucleus..  

The lateral spinal artery anastomoses rostrally with the branches of the posterior inferior cerebellar artery (PICA) at the restiform body and laterally with the extraspinal arteries at the emergence of each nerve.  

Only rarely are fibers found in either the restiform body or the brachium pontis.  

Mapping sites from which CCN cells were antidromically activated showed that axons of the CCN-SCT cross at the same segment, ascend the ventral funiculus initially, the lateral funiculus at rostral C1 and the lateral border of the medulla to reach the cerebellar peduncle, enter the cerebellum mainly via the restiform body but possibly also via the superior peduncle.  

Most fibers ascended through the ipsilateral restiform body, but a few fibers ran on the contralateral side.  

Inhibitory projections from floccular Purkinje cells reach the ipsilateral vestibular nucleus via the restiform body and selectively control certain VORs. We examined the ocular functions in a patient with a lateral lower pontine infarct that included the restiform body.  

Axons of labeled TC cells course laterally through the spinal trigeminal tract, enter medial aspects of the restiform body, and arch dorsally into the cerebellum..  

This syndrome of ocular lateropulsion probably results from a lesion of the restiform body interrupting cerebello-vestibular connections, associated with a lesion of the inferior part of the vestibular nuclei..  

This includes a periventricular region dorsolateral to the fourth ventricle corresponding to the A4 group, the white matter separating vestibular and intracerebellar nuclei, and lateral to the vestibular complex in relation to the restiform body.  

The size of the N2 wave from contralateral cerebral cortex is reduced to about half of the original size after electrolytic lesion of either the brachium pontis (BP) or the restiform body (RB) ipsilateral to the recording site, while only a small reduction in the size of N2 is observed after lesions of contralateral BP and RB.  

The nuclei gracilis and cuneatus, restiform body and ventral spinocerebellar tracts were all involved in the brain stem.  

Motor effects produced by microstimulation of restiform body (RB) were studied in acute unanesthetized cats, using tungsten electrodes for stimulating the peduncle and bipolar steel electrodes for recording muscular activity (EMG).  

The paratrigeminal nucleus, a diffuse collection of neurons on the lateral medullary surface, lies embedded in the fibres of the restiform body, ascending spinocerebellar tract and the spinal tract of the trigeminal nerve.  

When the contralateral dorsal and intermediate acoustic striae are lesioned as they pass over the restiform body, ipsilateral clicks inhibit even if they are substantially less intense than contralateral clicks.  

Degeneration also coursed around the superior surface of the restiform body and was traced into the dorsal and intermediate acoustic striae.  

Fibers from the LRN ascend the ipsilateral restiform body, terminating bilaterally but chiefly in the ipsilateral cerebellum.  

Serial sections through the medulla oblongata, impregnated with the Fink-Heimer technique, show that fibers ascending from brachial levels in the dorsal part of the lateral funiculus reach the cuneate nucleus either by a dorsomedial route through the tegmentum or by cuneate nucleus either by a dorsomedial route through the tegmentum or by ascending in the restiform body.
