The eyes then turn toward the ipsilateral ear, with horizontal nystagmus to the contralateral ear. [5] [6] Absent reactive eye movement suggests vestibular weakness of the horizontal semicircular canal of the side being stimulated. In comatose patients with cerebral damage, the fast phase of nystagmus will be absent as this is controlled by the ...
The vestibulocochlear nerve or auditory vestibular nerve, also known as the eighth cranial nerve, cranial nerve VIII, or simply CN VIII, is a cranial nerve that transmits sound and equilibrium (balance) information from the inner ear to the brain. Through olivocochlear fibers, it also transmits motor and modulatory information from the superior ...
53401. Anatomical terms of neuroanatomy. [ edit on Wikidata] The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other). In humans the vestibular nerve transmits sensory information from vestibular hair cells located in the two otolith organs (the utricle and the saccule) and the three ...
The paramedian pontine reticular formation ( PPRF) (also known as paraabducens nucleus) is a subset of neurons of the oral and caudal pontine reticular nuclei mediating horizontal gaze. [ 1] It is situated in the pons adjacent to the abducens nucleus. [ 2] It projects to the ipsilateral abducens (cranial nerve VI) nucleus, and contralateral ...
Nystagmus. Nystagmus is a condition of involuntary (or voluntary, in some cases) [1] eye movement. [2] People can be born with it but more commonly acquire it in infancy or later in life. In many cases it may result in reduced or limited vision. [3] In normal eyesight, while the head rotates about an axis, distant visual images are sustained by ...
The vestibular system, in vertebrates, is a sensory system that creates the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals . As movements consist of rotations and translations ...
242787. Anatomical terms of neuroanatomy. [ edit on Wikidata] In neuroanatomy, the ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. [ 1 ][ 2 ] Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF).
The study, undertaken by scientists at the Max Planck Institute, challenges long-standing views and could lead to new treatment approaches for the disease. Although Alzheimer’s disease remains ...
