Embodiment 1

[0022] see figure 1 , the drug addiction assessment method combining EEG and near-infrared, including PC host (Ⅰ), experimental paradigm module (II), EEG acquisition module (Ⅲ), near-infrared acquisition module (IV) and evaluation algorithm module (Ⅴ) . It is characterized in that the host (I) is connected to the experimental paradigm module (II), EEG acquisition module (III), near-infrared acquisition module (IV) and evaluation algorithm module (V), and is characterized in that: the PC host (I ) is mainly responsible for the operation of all module software programs. The experimental paradigm module (II) is composed of the Eprime experimental paradigm program (1). It is designed for drug addicts to induce the activation of neurons in different brain regions of the brain through specific stimulus picture presentation modes, and generate related brain activities. The information is transmitted to the EEG acquisition module (Ⅲ) and the near-infrared acquisition module (Ⅳ); the ...

Embodiment 2

[0024] This embodiment is basically the same as Embodiment 1, and the special features are as follows: the experimental paradigm module (II) is an experimental paradigm shared by EEG and near-infrared. In the experimental paradigm, drug pictures and all neutral pictures are presented, and each Each picture has a number as a label. The program design takes into account the characteristics of rapid EEG changes and prolonged oxygen metabolism in the blood; the program has made a precise design for the arrangement of each picture, which makes EEG and near After infrared is combined with hardware, the experimental paradigm can be shared well. The EEG acquisition module (Ⅲ) uses the 64-lead electrode cap (2) to connect to the wireless amplifier (3), and the wireless amplifier (3) is connected to the 5G router (5) in a wireless manner, and the Triggerbox marks the box (4) It is connected to the PC host (I) through the parallel port, and it is also connected to the 5G router (5) throu...

Embodiment 3

[0026] Such as figure 1 As shown, this drug addiction assessment method combining EEG and near-infrared includes PC host, Eprime experimental paradigm program (1), 64-lead electrode cap (2), wireless amplifier (3), and Triggerbox marking box (4) , 5G router (5), portable NIRSIT (6), USB cable (7) time domain analysis and evaluation algorithm program (8).

[0027] In the EEG module, the 64-lead electrode cap (2) is connected to the wireless amplifier (3), the Eprime experimental paradigm program (1) is connected to the Triggerbox marking box (4) through the parallel port, and the wireless amplifier (3) is connected to the Triggerbox marking box (4) Connect with the 5G router (5) in a wireless form. The communication between the PC host and the 5G router (5) is in the form of TCP / IP, and receives data and labels from the 5G router (5); the near-infrared module uses a portable NIRSIT (6) which uses a USB cable (7 ) form is connected to the PC host, and the collected near-infrar...

Abstract

The invention discloses an electrocerebral and near-infrared combined drug addiction assessment method. A PC host is responsible for operation of all module software programs, and an experimental paradigm module is composed of an Eprime experimental paradigm program, designed for patients abstained from drugs, induces activation of neurons in different brain regions of a brain through a specific stimulated picture presentation pattern to generate relevant brain activity information, and transmits the relevant brain activity information to an electrocerebral collection module and a near-infrared collection module; the electrocerebral collection module collects electrocerebral signals in the brain activity information under the effect of the Eprime experimental paradigm program through TCP / IP; the near-infrared collection module collects oxyhemoglobin signals and deoxyhemoglobin signals in the brain activity information under the effect of the Eprime experimental paradigm program; and anassessment algorithm module identifies and assesses the severity degree of drug addiction of the patients abstained from the drugs by adopting a support vector machine classifier through informationobtained by the electrocerebral collection module and the near-infrared collection module.

Description

technical field [0001] The invention relates to a drug addiction assessment method combining EEG and near-infrared, and belongs to the field of national security and medical-industrial integration application. Background technique [0002] Nowadays, the world is developing with each passing day and the achievements are remarkable, but the problem of drugs, which plagues all mankind, has not been well resolved. The proliferation of drugs is still a complex global problem. Now the pattern of drugs is refurbished year by year, the number of drug addicts continues to rise, and the number of drug addicts tends to be younger. The drug problem, which is as famous as terrorism and AIDS, has seriously threatened the entire human being. How to successfully quit drug addiction has become the most urgent and thorny issue in the world. One of the sex problems. [0003] In terms of evaluating the degree of addiction of drug addicts, the existing evaluation can only rely on one-on-one psy...
