Neural signal feedback method and system for reducing smoking craving based on functional magnetic resonance

Abstract

The invention discloses a neutral signal feedback method and system for reducing smoking desire based on functional magnetic resonance. The neutral signal feedback method includes the steps that neural activity signals of the two insulae and the prefrontal lobe of a smoker are acquired in real time; the acquired neutral activity signals are analyzed in real time to recognize smoking desire signals and self-control signals and the intensity of the signals; the self-control signals, the smoking desire signals and the intensity of the signals are configured into training feedback of the dynamic confront process of two confront parties in a visualized confront game. By means of neutral signal feedback, a person desiring smoking is helped to perceive and control relevant brain regions, and then the purposes of enhancing the self-control capacity of the smoker, reducing the desire and assisting in smoking cessation are achieved.

Description

technical field [0001] The invention relates to a nerve signal feedback method and a nerve signal feedback system for reducing smoking craving based on functional magnetic resonance. Background technique [0002] Smoking addiction can lead to an increase in the prevalence of many related diseases. my country is the world's largest tobacco producer and consumer, and the proportion of smokers accounts for about one-third of the total number of smokers in the world. Like other substance dependencies, withdrawal rates for smoking addiction are very low. A survey shows that more than 75% of smokers have tried to quit smoking, but only 3% of them can quit successfully. Intense cravings to smoke are the main reason for high relapse rates. Therefore, effectively reducing the craving for smoking is the key to successful smoking cessation. [0003] At present, the method of reducing the craving for smoking is mainly externally administered substances, the most common ones are the ...

Problems solved by technology

[0005] At present, some people conduct research and use cognitive therapy to help smoking cessation, but because the effect is not ideal, it is generally used as an adjuvant therapy other than drug therapy. The relevant content is disclosed in Chinese patent applications 200510123267.0 and 01819228.9

Poor effect display may be the main reason for the unsatisfactory effect of cognitive therapy, that is, smokers who quit smoking cannot get timely and effective feedback, so they cannot choose effective strategies to reduce craving based on the effect feedback

[0006] In addition, the mechanism of action of most existing methods to reduce smoking craving is not clear. With the development of neuroimaging, more and more experimental evidence shows that the activity level of specific brain regions is closely related to the level of smoking craving
