Method for regulating and controlling cognitive ability through real-time neural feedback based on functional near-infrared spectroscopy (fNIRS)

Abstract

The invention relates to a method for regulating and controlling the cognitive ability through real-time neural feedback based on functional near-infrared spectroscopy (fNIRS). The method includes thestep of 12 times of real-time neural feedback regulation training conducted in sequence, each real-time neural feedback regulation training includes three experimental blocks, and each experimental block includes 12 experiments, wherein each experiment lasts for one minute, during the first 30 seconds, resting is conducted, a subject maintains a resting state, and during the later 30 seconds, regulating is conducted, specifically, regulating includes the steps that (1) a near-infrared brain imaging system is used for measuring a blood oxygen level signal of the brain of the subject; (2) collected blood oxygen level signal data are sent to an external computer in real time, and a blood oxygen level signal of a target brain area is real-timely presented to the subject in a stone rising andfalling / food picture blurring form; and (3) the subject is regulated in real time through psychological strategies according to the change of stone rising and falling or the change of the food pictureblurring degree, and as for objective regulating, stone is regulated to a high position and kept, or a food picture is blurred and kept in a blurred state.

Description

technical field [0001] The invention relates to a method for regulating cognitive ability by real-time neurofeedback based on fNIRS. Background technique [0002] At present, all countries in the world are facing the global problem of obesity, which is the third most threatening factor to human health after cardiovascular disease and cancer. In 2016, the famous British medical journal "The Lancet" published a survey report on the weight of global adults: the obese adult population in the world has exceeded the normal weight, and China has 90 million obese people (43.2 million males and 46.49 million females) exceeding the 87 million in the United States. , becoming the country with the largest obese population in the world. Therefore, the obesity situation in our country is very serious. [0003] Obesity not only causes various metabolic diseases (type II diabetes, etc.), but also causes various complications, such as coronary heart disease, hypertension, liver and gallbla...

Problems solved by technology

In addition, obesity seriously affects people's quality of life, reduces social acceptance, reduces income, increases psychological burden, and increases the burden on the public health system; the cost of obesity accounts for about 2%-10% of total medical expenses

The clinical treatment of obesity shows that the efficacy of drugs to lose weight is not satisfactory, and it is accompanied by side effects; while surgical bariatric surgery (bariatric gastric banding (AGB), sleeve gastric Surgery (RYGB)) has a long-term and effective effect on the treatment of obesity, but the cost of surgery is high, and there is a risk of weight gain after surgery

[0004] Studies have shown that there are many reasons for obesity, but the main factor is that obese patients cannot suppress their desire for high-calorie food, leading to excessive intake of high-calorie food, which leads to obesity

Existing studies have shown that the brain reward circuits of obese patients have a higher response to food picture stimuli, while the brain areas responsible for cognitive decision-making and executive control respond insufficiently, resulting in obese patients being unable to control their eating behavior
