The general visceral efferent component of the eighth cranial nerve.
Study of the brain stem, stato-acoustic nerve, and inner ear of the mouse by a cholinesterase technique has disclosed that the acetylcholinesterase-positive centrifugal fibers to the inner ear are part of a general visceral efferent system which supplies fibers to the facial, vestibular and cochlear nerves. This system largely corresponds in its central course to that of the bundle of fibers wh...
متن کاملAberrant regeneration of the third cranial nerve.
BACKGROUND Aberrant regeneration of the third cranial nerve is most commonly due to its damage by trauma. CASE A ten-month old child presented with the history of a fall from a four-storey building. She developed traumatic third nerve palsy and eventually the clinical features of aberrant regeneration of the third cranial nerve. The adduction of the eye improved over time. She was advised for...
متن کاملTeaching neuroimages: Compression of the eighth cranial nerve causes vestibular paroxysmia.
A 55-year-old man reported having recurrent spontaneous attacks of rotatory vertigo lasting 1–5 seconds and occurring up to 10 times daily and often associated with attacks of right ear tinnitus for more than 3 years. Caloric testing showed a right peripheral vestibular deficit. Cervical vestibular myogenic potentials showed impaired function of the right saccule. An audiogram was normal. MRI (...
متن کاملPromoting central nervous system regeneration: lessons from cranial nerve I.
The olfactory nerve differs from cranial nerves III-XII in that it contains a specialised type of glial cell, called 'olfactory ensheathing cell' (OEC), rather than Schwann cells. In addition, functional neurogenesis persists postnatally in the olfactory system, i.e. the primary olfactory pathway continuously rebuilds itself throughout adult life. The presence of OECs in the olfactory nerve is ...
متن کاملHearing thresholds and FMRI of auditory cortex following eighth cranial nerve surgery.
OBJECTIVE Determine whether auditory cortex (AC) organization changed following eighth cranial nerve surgery in adults with vestibular-cochlear nerve pathologies. We examined whether hearing thresholds before and after surgery correlated with increased ipsilateral activation of AC from the intact ear. STUDY DESIGN During magnetic resonance imaging sessions before and 3 and 6 months after surg...
