Temporal correlation of the stimulus paradigm with physiological noise induced by cardiac activity, blood flow, blood pulsation and respiration affects the BOLD signal. Realizing the unmet needs of todays fMRI studies this abstract focuses on the monitoring and tracking of multiple physiological signals including ECG, phonocardiogram, magneto-hydrodynamic effect, pulse oximetry, respiration etc. to examine physiological fluctuations. For this purpose a dedicated physiological logging device that facilitates simultaneous and synchronized recording of multiple physiological signals as well as of the scanner trigger in-/output is proposed.
