Abstract

The invention discloses a depression electroencephalogram neural feedback method and system, and the method employs an optimized quadratic programming feature selection method, effectively selects an optimal electrode in a global range, reduces 64 leads to 20 leads, greatly reduces the subsequent calculation amount, and improves the real-time performance of feedback. Then, instantaneous change of the amplitude of the electroencephalogram signal is captured by adopting a rapid transition process method, and further a structure synchronization index and a brain connection asymmetry index are calculated; and finally, based on the calculated brain connection asymmetry index, adaptive adjustment is performed on the brain region, so that the cooperative control degree between the left hemisphere network and the right hemisphere network of the brain can be reflected, and the nerve mechanism of depression can be better analyzed from the angle of index change.

Description

technical field [0001] The invention relates to an EEG neurofeedback method and system for depression, belonging to the technical field of brain function diagnosis. Background technique [0002] Brain science has become one of the hotspots in the field of contemporary scientific research, and it is widely used in clinical diagnosis due to its non-invasive, high temporal resolution and other characteristics. When the human body receives stimuli such as vision, hearing, and touch, the potential of the electroencephalogram (Electroencephalogram, EEG) will change regularly. The functional connectivity of the brain is also widely used in the research of various medical problems because it can reflect the interaction of different brain regions. Therefore, the research and analysis of brain functional connectivity on EEG not only reduces the psychological burden of the subjects, but also reflects the coordination of brain regions at different times. [0003] Today, depression has...
