Integrated device for modulating and detecting brain functions

Abstract

The invention discloses an integrated device for modulating and detecting brain functions. A silicon rubber case is sleeved on the surface of a transcranial magnetic stimulation coil, an inner ring and an outer ring of the silicon rubber case are provided with a plurality of holes at different distances, near infrared transmitting and receiving probes can be conveniently inserted into the holes, the probes can be firmly held by the aid of elasticity of silicon rubber, the upper positions and the lower positions of the probes can be optionally adjusted, and close contact of the probes and the scalp of a detected portion is ensured. A miniature near infrared brain function detection device sets frequencies through a microprocessor, the frequencies are transmitted and received by a near infrared ray with a 690nm wavelength and a near infrared ray with a 830nm wavelength respectively, a plurality of LD (laser diode)/LED emitting light sources distributed at the center of the stimulation coil are sequentially lightened in a time-sharing multiplexing mode, signals detected by the surrounding probes are processed, changes of deoxyhemoglobin and blood flow are displayed on a liquid crystal display screen, and changes of the strength, the range and the depth of brain function activities corresponding to each detection channel through transcranial magnetic stimulation are reflected.

Description

technical field [0001] The invention relates to an integrated device for brain function modulation and detection. In particular, it relates to a method and an integrated device for simultaneously implementing non-invasive transcranial magnetic stimulation and miniature near-near-infrared brain function detection technology. Background technique [0002] Transcranial Magnetic Stimulation (TMS) is a new technology of non-invasive cerebral cortex stimulation and modulation that appeared after 1985, and has been widely used in brain science research, clinical diagnosis and treatment. TMS uses a pulsed transient magnetic field to pass through the skull unhindered and painlessly, and induces an electric current in the brain to stimulate the cerebral cortex nerves to produce a series of physiological effects and biochemical reactions. TMS affects all levels of molecules, synapses, cells, networks, functional areas, system structures, and decision-making behaviors in neuroscience; ...

AI Technical Summary

Problems solved by technology

Near-infrared brain functional imaging equipment transmits and receives through optical fibers. Although optical fibers are free from electromagnetic interference, it is difficult to move and operate the stimulating coil of TMS on the head densely covered with optical fibers, and too many optical fibers are fixed on the head frame. It is time-consuming and troublesome. The stimulation coil of TMS cannot approach the skull in the middle of the optical fiber for effective positioning and accurate stimulation of the target area of ​​the cortex, making it difficult for the current TMS and fNIRS to work at the same time.
