Abstract

The invention discloses a manufacturing method of an artificial vestibular organ and a research method of vestibular nuclear electro-stimulation for the artificial vestibular organ. Head motion information is transmitted to a central nervous system through electro-stimulation of brainstem vestibular nucleus, and the novel artificial vestibular organ is developed. The artificial vestibular organic is made first, horizontal rotational signals are detected through an angular velocity sensor so as to modulate the frequency of electrical impulses, vestibular nerve endings of a dominant horizontal semicircular canal of an experimental animal are electrically simulated, horizontal rotation of eyeballs is caused, existing methods and devices are modified to deeply research brainstem vestibular nuclear electro-stimulation, basis for related clinical application and fundamental research of artificial vestibular organs in the future is laid, and high social and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of medical research, and in particular relates to a manufacturing method of an artificial vestibular organ and a research method for electrically stimulating vestibular nerve nuclei. Background technique [0002] Current research on artificial vestibular organs mainly focuses on electrical stimulation of the vestibular nerve. The nerves innervating the three semicircular canals are relatively easy to locate during surgery. In the natural state, the neural information transmission of the normal vestibular organ is relatively close to the pulse frequency code, so the artificial vestibular organ manufactured in this way is relatively close to the normal organ, and the incoming information is easily accepted by the central nervous system. However, if the patient's vestibular nerve does not exist due to various reasons (such as surgical cut-off, etc.), the artificial vestibular organ in this way is completely inapplicable...
