Problems solved by technology

[0010] At present, most of the behavioral studies of neurostimulation require the stimulation signal generated by the stimulator to act on the electrode array interfaced with the nerve tissue through the wire, or the evoked response signal of the nerve stimulation is returned to the recorder through the wire. This wired connection The method hinders the freedom of animal behavior, so that the research results cannot truly reflect the effect of neural stimulation
Especially where multi-channel stimulation or recording is required, the length and degrees of freedom of the wire harness are limited

Embodiment 1

[0023] Embodiment 1: as Figure 1-2 As shown, a wireless deep brain neural interface system includes a computer 1, RS2322, a transceiver module 3, an antenna 4, an external transceiver 5, a subdural transceiver 6 and a wireless deep brain neural interface 7 for constructing external Forward access and for inward backward access;

[0024] For the outward forward path: the computer 1 inputs the stimulation parameters and transmits them to the transceiver module 3 through RS2322. The device 5 demodulates and amplifies the signal sent by the received transceiver module 3, converts the amplified demodulated signal into a corresponding ultrasonic energy beam and transmits it to the subdural transceiver 6, and the subdural transceiver 6 The first group of stimulating probes is received by the ultrasonic signal transmitted by the external transceiver 5 to drive the vibration, and the first group of stimulating probes in the subdural transceiver 6 pass through the electric current gener...

Abstract

The invention discloses a wireless deep brain neural interface system, which belongs to the technical field of physiology and brain science. The present invention includes computer, RS232, transceiver module, antenna, external transceiver, subdural transceiver and wireless deep brain neural interface 7 for constructing outward forward pathway and inward backward pathway. The invention not only provides a path for the external device to stimulate the neuron, but also provides a path for the external device to collect the electroencephalogram signal.

Description

technical field [0001] The invention relates to a wireless deep brain neural interface system, which belongs to the technical field of physiology and brain science. Background technique [0002] With the rapid development of neuroscience, computer science, signal processing and other technologies, the communication and control between the brain and computers or other equipment is realized, and severely paralyzed patients can control external equipment with their thinking or consciousness. Reality. The system that accomplishes this function is called a neural interface (Neural interface, NI). [0003] Neural interface research is an interdisciplinary science involving neurophysiology, computing science, and microelectronics technology. It has important research value in rehabilitation engineering and other fields, and has developed rapidly in recent years. It mainly studies the interface between biological nervous system (including sense organs and executive body) and moder...
