2019, Current Opinion in PhysiologyCitation Excerpt :In primates, however, LVST-neurons do not appear to have brainstem collaterals [18]. Individual LVST axons have putative synaptic contacts through large portions of the ventral spinal cord, can collateralise at several spinal levels ([19]; Figure 1a) and can innervate multiple extensor motor neuron pools [9]. In mice, LVST axons are found throughout the ventral grey matter [9,20,21], with dense projections around both the lateral and medial motor columns (the location of limb and axial motor neurons, respectively).
Physiology of central pathways
2016, Handbook of Clinical NeurologyCitation Excerpt :VO neurons in the VN project to the cervical spinal cord and are thought to mediate the VCR pathway (Fig. 2.5) (Wilson et al., 1990; Boyle, 1993; Boyle et al., 1996; Gdowski and McCrea, 1999). Additionally, projections from vestibulospinal axons to both the cervical and/or lumbar levels of the spinal cord (Abzug et al., 1974; Rapoport et al., 1977; Shinoda et al., 1988) coordinate different parts of the musculature, for example, the neck and axial muscles during head movement to ensure stable posture. Similar to the VOR, the most direct pathway connecting the vestibular nerve and spinal cord motoneurons is a three-neuron arc.
Multisensory Signaling Shapes Vestibulo-Motor Circuit Specificity
2015, CellCitation Excerpt :In the vestibular system, one central sensory organ in the inner ear monitors linear and rotational acceleration and provides input to the vestibular nucleus of the brainstem (Angelaki and Cullen, 2008; Brodal and Pompeiano, 1957). Descending vestibulo-spinal projection neurons transmit this information to spinal circuits to provide postural stability (Grillner et al., 1970; Lund and Pompeiano, 1968; Shinoda et al., 1988; Wilson and Yoshida, 1968). The somatosensory system represents a complementary signaling system in which sense organs are distributed throughout the entire body (Abraira and Ginty, 2013; Brown, 1981; Matthews, 1981).
Differences between otolith- and semicircular canal-activated neural circuitry in the vestibular system
2011, Neuroscience ResearchCitation Excerpt :In this set-up, the interneurons of the vestibular nuclei play an important role as a sensory motor terminal that drives motor neurons in the spinal cord (Wilson and Maeda, 1974; Rapoport et al., 1977a,b; Fukushima et al., 1979; Wilson and Melvill Jones, 1979). Similar to the vestibulo-oculomotor system, the vestibular nuclei interneurons are classified as vestibulo-collic (VC) and VOC neurons, with or without ascending axon collaterals to the oculomotor nuclei, respectively (Wilson and Maeda, 1974; Rapoport et al., 1977a,b; Wilson et al., 1979; Uchino and Hirai, 1984; Isu et al., 1988; Shinoda et al., 1986, 1988; Uchino et al., 1988, 1990; Uchino and Isu, 1992b). The VC neurons that send long axons as far as the lumbar segments of the spinal cord are distinctively termed vestibulo-spinal (VS) neurons in this review.
