Baseline drift and physiological (cardiac and respiratory) fluctuations are among major sources contaminating blood oxygenation level dependent (BOLD) signals in high field functional magnetic resonance imaging (fMRI). Automatically detecting and removing them have been long-standing problems. We propose here a new method, utilizing kernel principal(More)
While the recording of extracellular monophasic action potentials (MAPs) from single epicardial or endocardial sites has been performed for over a century, we are unaware of any previous successful attempt to record MAPs simultaneously from a large number of sites in vivo. We report here the design and validation of an array of MAP electrodes which records(More)
