PROBLEM TO BE SOLVED: To provide a technique capable of helping elucidation of the mechanism existing between the mode of EEG and the severity of depression. A stimulus applying unit (111) for applying an electromagnetic stimulus to a first region (visual cortex 30) of a subject's brain, and a second region of the brain (motor area 50) different from the first region. (112) for measuring an electroencephalogram and a transmission time deriving section (113) for deriving a transmission time, which is a time required for the stimulus to be transmitted to the second region, from the electroencephalogram measured by the measurement section. An electroencephalogram signal processing device (11) comprising: [Selection diagram] Figure 1
