Abstract: An arrangement and method for ascertaining and recording electrophysiological signals associated with a subject are provided. In particular, first (or motion) data associated with a movement of the subject from one or more motion sensors can be received. Such movement may include a head movement by the subject, swallowing by the subject, etc. The first data also can include noise associated with a blood flow motion within the subject, noise associated with a ballistocardiac motion within the subject, etc. Second data associated with intrinsic voltages measured may also be received from the subject. Then, output or result data can be calculated based on the first motion data and the second data. The output (or result data) is preferably associated with the electrophysiological signal. In an exemplary embodiment, a continuous, real time display of electrophysiological signals that is associated with the output data can be generated.
