To provide a mechanism for stabilizing a
brain state with an application.SOLUTION: A
living body state stabilization support device includes: a
living body information acquisition unit 11 for acquiring biological information generated when a patient and a healthy person having close relationships with the patient execute an assignment jointly from both the patient and the healthy person; and a stabilization evaluation unit 12 for evaluating a stabilization degree of the patient's
brain state from the viewpoint of whether or not the patient's biological information and the healthy person's biological information are tuned or synchronized with each other. A degree of stabilization of the patient's
brain state is evaluated using the character of the biological information generated from the healthy person whose brain state is stabilized and the biological information generated from the patient sympathizing with the healthy person becoming tuned or synchronized with each other, and joint experiences are repeated while the patient and the healthy person change the assignments properly, thereby enabling the patient's brain state to be stabilized more.SELECTED DRAWING: Figure 2
