There are four 2nd order vestibular nuclei: the inferior, medial, lateral (Deiter’s) and superior vestibular nuclei. All four nuclei are found beneath the floor of the fourth ventricle in the medulla and pons, lateral to the sulcus limitans.

Sensory(proprioceptive), vestibular, and cerebellar. farthest from the midline, of the four pairs of deep cerebellar nuclei, the others being the fastigial [].

Some vestibular efferent projections to reticular formation, dorsal pontine nuclei, and nucleus of solitary tract. Function: Stabilize respiration and blood pressure during body motion and changes relative to gravity Role in motion sickness The vestibular nuclei are aligned within the rhomboid fossa in such a way that they form two vertical columns, one medial and one lateral. In the medial column is the medial nucleus, whereas the inferior, lateral and the superior nuclei form the lateral column. These nuclei contain the bodies of second-order neurons of the vestibular pathway.

Vestibular nuclei

Function. maintain visual fixation during body movement (all vestibular nuclei), adapt axial tonus to body movements (lateral, medial vestibular nuclei), Another neuron, located in the right vestibular nuclei, had a comparable response to contralateral rotation (left, CCW, Type II), but a much smaller response to rotation toward the ipsilateral side (Figure 4B). The sensitivities of such neurons are shown in Table 1 (second block from the top) and are summarized in Figure 4F (gray symbols). The vestibular nerve travels to the medulla where it synapses on four vestibular nuclei. This happens bilaterally.

Cookie-policy; To contact us: mail to admin@qwerty.wiki The nuclei and pathways are interconnected ipsilaterally and contralaterally which helps in coordination and synchronization of movements. They are also connected to the cerebellum which allows for coordination and fine-tuning.
