Brain function network evolution modeling method for sensorineural deafness

Abstract

The invention discloses a sensorineural deafness brain function network evolution modeling method, which comprises the following steps: S01, extracting brain network state data, taking a BOLD signal of a resting state fMRI as an object, analyzing and extracting the state expression of a brain network through a sliding window technology, and obtaining the high-dimensional vector expression of the brain network state; s02, acquiring a low-dimensional mapping and clustering result by using the state observation matrix; s03, analyzing a conversion mode of the brain network state, constructing a state set according to a clustering result of the state, analyzing a relationship between state switching and time, and obtaining a time sequence diagram of brain network state evolution on a time axis; s04, on the basis of the brain network evolution model of the timed automaton, according to the brain network state evolution sequence diagram, establishing an evolution process model through the timed automaton theory, a quantitative brain network dynamic description model is provided, and the state transition rule and the evolution process of the human brain network can be effectively described. The method has universality for different tested data, and abnormal evolution process of the subject can be identified.

Description

technical field [0001] The embodiment of the present invention relates to the field of medical equipment, in particular to a portable sharps box. Background technique [0002] Deafness is one of the common diseases that seriously affects human health and life. The incidence rate in adults accounts for nearly 10%, and with the increase of age, the incidence rate of deafness shows a clear upward trend. The perception of sound depends on a series of complex structures. This series of structures includes not only the collection and transmission of sound by the ear, but also the transmission and analysis of the corresponding auditory nerve and auditory nerve center. [0003] At present, although the research on the brain function network of sensorineural deafness has achieved certain results, there are still several problems that need to be solved urgently. First, as the disease progresses, the brain function of patients with sensorineural deafness is still unclear. How to evolv...
