Method for extracting dynamic connection activity mode of seaman brain function network

Abstract

The invention discloses a method for extracting a dynamic connection activity mode of a seaman brain function network. The method comprises the following steps of: 1, acquiring brain resting state functional magnetic resonance imaging data of a seaman subject and a non-seaman subject; 2, performing preprocessing operation on the collected data; 3, obtaining a plurality of groups of resting-state brain function networks at the level and the individual level and corresponding time processes; 4, calculating a dynamic function connection matrix and a corresponding dynamic function connection vector between brain function networks corresponding to each tested person in the seaman and non-seaman data; and 5, extracting a seaman-specific brain function connection mode implied in the dynamic function connection matrix from the dynamic function connection vector. According to the method, the specific brain function connection mode of the seaman occupational group can be obtained according to dynamics; and the seaman dynamic brain function connection mode extracted by adopting the method can provide a basis for further research and analysis of seaman nerve activity rules and occupational brain plasticity.

Description

technical field [0001] The invention relates to the technical field of medical imaging image processing, in particular to a method for extracting a dynamic connection activity pattern of a seaman's brain function network. Background technique [0002] As a special occupational group, the working conditions of seafarers are quite different from those on land, and they are easily affected by many complex factors such as the natural environment and working environment, resulting in psychological distress of seafarers. This poor mental health not only affects the physical and mental health of seafarers themselves, but also poses great safety hazards to navigation operations. Therefore, it is particularly important to detect seafarers with mental sub-health conditions in advance and provide them with psychological counseling. In recent years, the mental health of seafarers has drawn more and more attention from the society, especially from the shipping industry. However, to the...

Problems solved by technology

[0004] However, current research mainly focuses on static functional connectivity, and the brain is a complex structure, and the functional connectivity between different brain regions changes dynamically over time. For special occupational groups, this dynamic change is often abnormal. Will be reflected in the abnormality of the corresponding brain functional connectivity
