Description: Physiological signals such as cardiac and respiratory rate have been found to strongly contribute to non-neuronal signal change of the BOLD contrast. New technologies allow to capture respiratory signal directly with sensors within the patient table without the use of a belt, which drastically increases subjects’ comfort. However, little is known about how effective these devices are. In this project, two different devices (respiration belt, spine coil recording) implemented into a Magnetom Vida MRI scanner, were compared in their suitability to capture respiratory signal during a perception task and during rest.
