Recording of The Evoked Potentials During Functional MRI: Applications in Cognitive Neuroscience
The feasibility of recording event-related potentials (ERP) during functional MRI (fMRI) scanning using higher-level cognitive stimuli was studied. Using responses to illusory figures in a visual oddball task, evoked potentials were obtained with their expected configuration and latencies. A rapid stimulation scheme using randomly varied trial lengths was employed, and class-wise characteristics of the hemodynamic response were obtained by a non-linear analysis of the fMRI time-series. Implications and limitations of conducting combined ERP-fMRI experiments using higher-level cognitive stimuli are discussed.
