A mobile communication device capable of communicating with a remote communication device includes a communication unit, a microphone, an input unit, a control unit, and a switching unit. The integrator integrates an input signal to output an integral signal. Information in the blood flow navigator data is used to reduce errors in the fMRI data due to tissue motion caused by pulsatile blood flow.
