Abstract

The invention discloses a closed loop-type near-infrared brain stimulation device, which comprises a computer, an acquisition and transmitting card, a constant current source, a near-infrared laser, a microelectrode and a differential amplifier, wherein the computer and the acquisition and transmitting card are interconnected via a data line; the I / O interface at the output end of the acquisition and transmitting card is connected with the signal input end of the constant current source; the output end of the constant current source is connected with the signal input end of the near-infrared laser; near-infrared lights outputted by the near-infrared laser irradiate on the head part of a human being; and the input end of the microelectrode acquires cranial nerve electric signals, the output end of the microelectrode is connected with the input end of the differential amplifier, and the output end of the differential amplifier is connected with the A / D interface at the input end of the acquisition and transmitting card. The closed loop-type near-infrared brain stimulation device has the advantages of simple structure, convenient operation and control, high stimulation precision and the like.

Description

technical field [0001] The invention belongs to non-destructive testing technology, in particular to a brain stimulation device. Background technique [0002] Neurological diseases are difficult to be cured by drugs and other means. Fundamentally speaking, various sensory and motor functions of the human body are the result of corresponding nerve cells or muscles receiving various stimuli to generate action potentials. When the function is abnormal, it can be cured by establishing nerve channels and applying external stimulation. Nervous system diseases include central and peripheral nervous system diseases, manifested as sensory, consciousness, motor and other nerve dysfunction, leading to epilepsy, stroke, Parkinson's disease, Alzheimer's disease and migraine, etc. Nervous system diseases have seriously affected the quality of life of patients and their families, and at the same time caused a heavy economic burden to families and society. [0003] Stimulation methods cur...
