BRAIN ACTIVITY TRAINING DEVICE AND BRAIN ACTIVITY TRAINING SYSTEM

摘要

Provided is a brain activity training device for performing a training modifying correlation of connectivity between brain areas, using correlation of measured connectivity between brain areas in feedback information. A correlation matrix is derived for the activity degree between predetermined brain regions for each subject, from data of functional connectivity MRI at rest measured in a group of healthy subjects and in a group of patients (S102). Feature extraction is performed (S104) by regularized canonical correlation analysis on the correlation matrix and on subjects characteristics containing subjects patients/healthy labels. Based on the results of the regularized canonical correlation analysis, a discriminatory analysis (S106) is performed by sparse logistic regression and discriminants are generated (S108). The brain activity training device gives a score in feedback to subjects, based on the results of discriminants for data of functional connectivity MRI relative to the subjects.
