BIOPAC Systems products were recently used for neurophysiological mapping on a human subject inside a 7T scanner for a study at Auburn University. The study was also coauthored by two of our own BIOPAC members, Ken Graap and Alan Macy, and presented at the recent Society of Psychophysiology Research annual meeting in Atlanta, GA. The experiment aimed to pull physiological measurements (ECG, EDA, & EMG) from a human subject during fMRI data acquisition. Data was acquired using BIOPAC’s suite of MRI-compatible modules, leads, and electrodes including the ECG100C-MRI, EMG100C-MRI, and EDA100C-MRI and all connected to the powerful MP150 system.  The study successfully gathered both high quality, multichannel physiological data and submillimeter fMRI data in an ultra-high field MR environment. This type of data collection can lead to better understanding of the neural and physiological processes that underlie psychological constructs. With both our reliable equipment and passionate staff members, BIOPAC continues our commitment toward aiding and leading innovation in life science research.
