A system and method for detecting the state of cerebral cortex in disorders of consciousness

Abstract

The invention discloses a cerebral cortex state detection system for disturbance of consciousness, which comprises a brain response signal synchronous acquisition module, a response signal noise processing module and a cerebral cortex state detection algorithm module. The response signal synchronous acquisition module includes transcranial magnetic stimulation and magnetically compatible EEG equipment; the EEG cap adopts a 64-channel high-density EEG cap; the transcranial magnetic stimulation coil adopts an 8-shaped coil. The magnetic field was placed in the left dorsolateral prefrontal cortex (the F3 electrode position in the 10‑20 EEG system) perpendicular to the direction of the scalp. The invention fills up the blank of the state detection system and method of the cerebral cortex of the disturbance of consciousness. Compared with the current clinical research method, the present invention has the advantages of economy, convenience, simple calculation, strong applicability, suitable for clinical promotion and the like.

Description

technical field [0001] The invention belongs to the field of biomedical engineering, and specifically relates to a method based on engineering and informatics, which is used for detecting the state characteristics of the cerebral cortex of patients with impaired consciousness. Background technique [0002] At present, there is basically no mature and reliable method for detecting the cortical state of disturbance of consciousness clinically. Individual cutting-edge medical research institutions have carried out the detection of cortical reactivity in disturbance of consciousness based on resting-state EEG, event-related potential and functional magnetic resonance technology. However, there are serious defects in the above methods, which restrict the application of these methods in clinical practice. The details are as follows: the existing detection methods based on resting-state EEG must be based on the statistical results of large samples, and cannot provide individualize...

AI Technical Summary

Problems solved by technology

However, patients with impaired consciousness generally have severe brain damage, and it is difficult to preserve the corresponding neural pathways. Therefore, the scope of application of this method in clinical practice is narrow.

Although functional magnetic resonance technology can give individualized judgments, it can only identify patients with particularly good cortical conditions based on the results, but cannot provide numerical indicators for doctors to refer to. Moreover, this method is complicated to operate and expensive, and cannot Popularized in clinical application

At present, foreign countries have reported that a method similar to the present invention is used to detect the cortical state of disturbance of consciousness, that is, the disturbance complexity index, but the algorithm is extremely complex and time-consuming, and it is difficult to promote it in clinical applications.
