Classification of schizophrenia-associated brain regions in resting-state fMRI

Recently, advances in neuroscience have attracted attention to the diagnosis, treatment, and damage to schizophrenia-associated brain regions using resting-state functional magnetic resonance imaging (rs-fMRI). This research is immersed in the endowment of machine learning approaches for discriminating schizophrenia patients to provide a viable solution. Toward these goals, firstly, we implemented a two sample t -tests to find the activation difference between schizophrenia patients and healthy controls. The average activation in control is higher than the average activation of the patient. Secondly, we implemented the correlation technique to find variations on presumably hidden associations between brain structure and its associated function. Moreover, current results support the viewpoint that the resting-state function integration is helpful to gain insight into the pathological mechanism of schizophrenia. Finally, Lasso regression is used to find a low-dimensional integration of the rs-fMRI and their experimental results showed that SVM classifier surpasses nine algorithms provided the best results with good accuracy of 94%.
