Research of Implantable Nerve Electrodes for Neuroregulation

Abstract

The deep integration of human brain and computer through continuous high-throughput information interaction is an important development vision in the field of neural engineering. Brain-computer fusion technology can not only greatly improve the therapeutic effect of patients with various diseases such as motor disability, mental illness, sensory and perceptual impairment, but also directly transmit the massive information stored in the electronic computer system and high-speed numerical computing power to the human brain, thus giving individuals "super powers". The implantable neural electrode array is an indispensable interface device for developing a wideband brain-computer integrated intelligent system. On the one hand, the implantable electrode array can simultaneously ensure the precise time and waveform of neuronal action potential in a large range and with high precision, laying a solid foundation for fully extracting neural information and interpreting the activity of the brain neural network. On the other hand, by using implantable electrode arrays to write information to neurons with high spatial and temporal precision, not only can new information be directly introduced into the brain, but also may change the abnormal neural network activity of patients with neuropsychiatric diseases (such as Parkinson's disease, epilepsy, and major depression), so as to alleviate symptoms or treat diseases.
