Embodiment Construction

[0024] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0025] Such as figure 1 As shown, a method for analyzing brain functional connectivity for resting-state EEG signals provided by the present invention comprises the following steps:

[0026] Step S1: Obtain resting state EEG data.

[0027] In this step, EEG equipment can be used to collect resting-state EEG data of each experimenter in a resting state with eyes open or eyes closed. Alternative experimental paradigms include: (1) rest with eyes open; (2) rest with eyes closed; (3) rotation with eyes open and eyes closed. During data collection, it can be judged whether the experimenter has entered a lethargic state by observing the sleep-related waveform. The data collection time is generally recommended to be 5-10 minutes. In order to ensure the reliability of the results of microstate analysis and functional connectivity analysis, EE...

Abstract

The invention discloses a brain function connection analysis method oriented to resting-state EEG signals. The method includes the following steps of S1, obtaining resting-state EEG data; S2, preprocessing the resting-state EEG data; S3, conducting micro-state analysis on the preprocessed resting-state EEG data; S4, determining the type of micro-state of each time point; S5, calculating function connection within the duration time range of each type of micro-state. By means of the method, the limitation of the existing brain function connection analysis technology of resting-state EGG signalsis overcome.

Description

technical field [0001] The invention relates to a brain function connection analysis method oriented to resting state electroencephalogram signals. Background technique [0002] The human brain does not stop functioning when the eyes are open or closed (that is, the resting state). In the resting state, not only certain brain regions (such as silent network-related brain regions) will be activated, but there will also be functional connections or information exchanges between various brain regions (that is, functional connections). Understanding the brain's functional connectivity in the resting state is critical to our understanding of how the human brain works. Previous studies have found that factors such as cognitive processes, personality factors, age, gender, and encephalopathy all affect the functional connectivity of the human brain in a resting state. To understand the functional connectivity of the brain in the resting state, it is necessary to use certain brai...
