Vestibular nuclei

The vestibular nuclei ( " equilibrium cores " ) are four key areas in the hindbrain ( rhombencephalon ), in which the first neuron in the equilibrium orbit, so the nerve fibers of the vestibular nerve (part of the eighth cranial nerve ) ends. They are human medial to the inferior cerebellar stem, in the vestibular area of the fourth ventricle, so the rear of the bridge ( pons) and the Elongated marrow (medulla oblongata ).

Specifically, we distinguish:

• Superior vestibular nucleus ( Bechterew's nucleus, after Vladimir Mikhailovich Bekhterev )
• Medial vestibular nucleus ( Schwalbe - core )
• Inferior vestibular nucleus (Roller - core )
• Lateral vestibular nucleus ( Deiters nucleus ): he is the main coordinating center for information equilibrium, named after Otto Deiters ( 1834-1863 ). Damage leads to Bonnier 's syndrome.

The nuclei receive their afferents from the equilibrium organs in the inner ear, visual afferents from the eyes, spinal afferents mainly from the deep neck muscles and as a parent controlling the cerebellum. This information is integrated into the Vestibularkernen and coordinates and then transmitted depending on the function.

From these cores attract efferent fibers in other parts of the brain ( the thalamus ( here switching to consciousness, ie the cortex ), reticular formation, cerebellum ) to the motor neurons in the spinal cord, where according to need balancing stance and gait movements are initiated, and the eye muscle nuclei (nucleus nervi oculomotorii, nucleus nervi trochlear nucleus and nerve abducentis, see nystagmus).
