摘要： A bioelectric current estimation method includes acquiring position information of a nerve in a measurement target region of a subject for which magnetic data is measured with a magnetic sensor, the position information of the nerve being acquired based on a nerve image included in a morphological image of the measurement target region; acquiring a positional relationship between a position of the nerve and a position of the magnetic sensor, based on the acquired position information of the nerve and position information of the magnetic sensor when the magnetic sensor is positioned to face the measurement target region; and estimating a neural activity current, which is generated in association with neural activity of the subject, based on the acquired positional relationship and the magnetic data of the measurement target region measured by the magnetic sensor.
