Speaker: Prof. Patricia Figueiredo (Institute for Systems and Robotics, Lisbon)

Bio: Professor Patrícia Figueiredo is a biomedical engineer focusing on noninvasive imaging of human brain function. She leverages MRI and EEG to explore brain function in both healthy individuals and patients with neurological and psychiatric disorders. She obtained her DPhil degree in Neuroimaging from the University of Oxford in 2003 and currently is a Principal Investigator of the Evolutionary Systems and Biomedical Engineering Lab (LaSEEB) at the Institute for Systems and Robotics of the University of Lisbon. Figueiredo’s notable contributions have been recognized with several awards, including the Prize for Women in Science by L’Oréal Portugal.

Title: fMRI vs. Electrophysiology in Humans

Abstract: Because BOLD -fMRI probes neuronal activity indirectly and with a lag of a few seconds, based on neurovascular coupling mechanisms, several studies have attempted to clarify its neuronal correlates in humans by combining it with the simultaneous recording of the electroencephalogram (EEG). Like other electrophysiology techniques, EEG provides direct measures of neuronal activity with sub-millisecond temporal resolution, albeit poorer spatial resolution and coverage than BOLD -fMRI. In this talk, I will overview the main characteristics of electrophysiology relative to BOLD -fMRI as well as the evidence contributed by EEG -fMRI studies towards our understanding of the neuronal correlates of different types of BOLD -fMRI measurements.
