Problems solved by technology
[0003] In the past 5 years, more researches have been applied to the treatment of addiction. The feedback brain areas roughly cover the brain areas related to addiction, but the selection of brain areas is rarely driven by very clear theories and used to explain the training. effectiveness
In addition, the current rtfMRI technology is mostly based on the training of a single brain region and the signal of the feedback signal is relatively single, but the effect is unstable and there are large individual differences in the long-term effect

Embodiment Construction
[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0036] The present invention conducts real-time functional magnetic resonance neurofeedback training based on the state of the brain network related to cognitive control, and resists the craving for addiction by improving the level of self-control. Most of the researchers who conduct real-time functional magnetic resonance experiments use the brain imaging system TBV (Turbo-BrainVoyager) system under Brain Innovation to complete the training of neurofeedback, but TB...

The invention discloses a regulation cognitive control system and method for real-time functional magnetic resonance nerve feedback. A communications agreement is used for conveying brain signals generated by a magnetic resonance imager to TBV and matlab interfaces, a voxel decoding module performs preliminary screening on all voxels in a brain network according to a selected control layer level,and performs weight calculation to complete training of a classifier. A real-time functional magnetic resonance nerve feedback module calculates the brain signals which are transmitted according to abuilt classifier, judges the current cognitive control level probability value of the current brain, and performs nerve feedback training based on percentage switched from the probability value. Whenthe nerve feedback training takes repeated scanning, and the voxels selected by a space coordinate conversion module for the classifier are projected to local space of current scanning from normed space, so that the feedback training can accurately correspond to the same voxel. Through voxel state recognition of an individual cognitive control brain network, nerve feedback training of real-time magnetic resonance is performed, and the self cognitive control can be improved.
Description
technical field [0001] The invention belongs to the technical field of cognitive neuroscience, is based on cognitive science theory, and relates to a platform for adjusting self-cognitive control level by real-time functional magnetic resonance neurofeedback technology, and then regulating addiction craving. Background technique [0002] Addiction-related studies have found that different regions of the prefrontal cortex have abnormal activities under different tasks (eg, motor inhibition, attention orientation, and emotion regulation). The underlying cause of the abnormal activity in the prefrontal brain area is likely to be related to the decline of different levels of cognitive control, such as: seeing addictive substances and responding inappropriately to stimuli, seeing stimuli but not being able to respond to the situation. Making conditioning, stimulus and action linkages by memory inappropriate retrieval. Based on this, neurofeedback targeting different regions of t...
