Cranial nerve stimulating device for enhancing cognitive function of brain

Abstract

The invention provides a cranial nerve stimulating device for enhancing a cognitive function of a brain. The device comprises a frequency tunable high-frequency electromagnetic wave source, a beam shaping unit, an optical fiber coupler, a multi-dimensional fine tuning platform, an optical fiber, and an electrophysiology detecting device. The frequency tunable high-frequency electromagnetic wave source is used for generating high-frequency electromagnetic pulses. The beam shaping unit is used for shaping and focusing the high-frequency electromagnetic pulses generated by the frequency tunable high-frequency electromagnetic wave source to the input end of the optical fiber. The optical fiber coupler is used for fixing the input end of the optical fiber. The multi-dimensional fine tuning platform is used for fine tuning and aligning the input end of the optical fiber and a light spot. The optical fiber is used for receiving the high-frequency electromagnetic pulses and introducing the high-frequency electromagnetic pulses into the cranial nerve system through the output end of the optical fiber. The electrophysiology detecting device is used for detecting the tissue activity after thecranial nerve system is stimulated by the high-frequency electromagnetic pulses. According to the cranial nerve stimulating device for enhancing the cognitive function of the brain, the minimally invasive, high-targeting and high-efficiency regulation and enhancement of the nerve system of an animal are realized by accurately introducing the high frequency electromagnetic signal into the nerve system of the animal.

Description

Technical field [0001] The invention relates to the technical field of brain nerve stimulation, in particular to a brain nerve stimulation device for enhancing the cognitive function of the brain. Background technique [0002] As the main part of the nervous system of higher animals, the brain is distributed with a large number of nerve centers composed of nerve cells. It is also the main organ for animals to produce cognition. Cognitive function is the processing process of the body to recognize and acquire knowledge. Enhancing cognitive function can improve perception, memory and thinking ability. How to enhance the cognitive function of the brain has always been the direction of researchers' efforts. At present, we can adjust the activity of brain nerve tissue through neuroregulation, so that brain function can be enhanced. [0003] Neuroregulation is the use of implantable and non-implantable technologies to change the activity of central and peripheral nerves by physical or...

Problems solved by technology

[0004] The existing mainstream neural regulation stimulation methods include drug / chemical regulation, electrical stimulation regulation, optogenetic regulation, ultrasonic regulation, magnetic stimulation regulation, etc., but each method has unsatisfactory aspects. Medications, duration of medications, and side effects are difficult to manage

Although electrical stimulation can control the effect, it requires implantation of stimulating electrodes, causing greater trauma; magnetic stimulation regulation such as transcranial magnetic stimulation does not require implantation, but the targeting is poor and it is difficult to focus on specific action points; optogenetics The method can efficiently regulate nerve stimulation with high spatial resolution, but it relies on transgenic engineering and light-sensitive proteins; ultrasonic stimulation can directly stimulate with low invasiveness, but it is greatly affected by tissues, and it is easy to cause focus drift after passing through tissues of different densities , misalignment of the action point
