Provided is a method of analyzing brain activities for realizing a biomarker for neurological/mental disorder, based on brain function imaging. From measured data of resting-state functional connectivity MRI of a healthy group and a patient group, correlation matrix () of degree of brain activities among prescribed brain regions is derived for each subject. Feature extraction is executed by regularized canonical correlation analysis () on the correlation matrix () and attributes of the subject including a disease/healthy label of the subject. Based on the result of regularized canonical correlation analysis, by discriminant analysis () through sparse logistic regression, a discriminator () is generated.

Brain activity analyzing apparatus, brain activity analyzing method and biomarker apparatus

A training apparatususing a method of decoding nerve activity includes: a brain activity detecting devicefor detecting brain activity at a prescribed area within a brain of a subject; and an output devicefor presenting neurofeedback information (presentation information) to the subject. A processing devicedecodes a pattern of cranial nerve activity, generates a reward value based on a degree of similarity of the decoded pattern with respect to a target activation pattern obtained in advance for the event as the object of training, and generates presentation information corresponding to the reward value.
