摘要:
The brain effective connectivity networks characterize the causal interactions of neural activity between brain regions. Researches on brain effective connectivity networks of different populations can not only provide a new perspective for understanding the pathological mechanism of neuropsychiatric diseases, but also provide novel brain network imaging markers for the early diagnosis and evaluation for treatment of diseases, thus have very important theoretical and practical value. Using computational approaches to identify brain effective connectivity networks from functional magnetic resonance imaging (fMRI) data is currently an important subject in the human brain connectome. This paper firstly summarizes a workflow of identifying brain effective connectivity networks from fMRI data and illustrates its main processes and methods. Next, a comprehensive category system of identifying brain effective connectivity networks is presented, and several typical identifying algorithms in each category are described. Finally, by analyzing challenging problems in this area, we predict the further research directions in identifying brain effective connectivity networks and hope to present some references for related researches.
