One of the major functions of the human brain is to mediate interactions with other people. Until recently, studying brain social interactions has not been possible due to the lack of measurable methods to observe two interacting minds simultaneously. We have developed a novel twin-head MRI coil that can scan two subjects brains simultaneously while the subjects are socially interacting in one MRI scanner. Meanwhile, an even-odd mode scheme for decoupling two quadrature coils (not surface coils) is validated.
