Marlon Gomes Calixto is an undergraduate student in Medical Physics and a participant in a Scientific Initiation program at the University of São Paulo (USP). His research focuses on the field of biomagnetism, with a particular emphasis on the Magnetoencephalography (MEG) system and the application of optically pumped magnetometers (OPMs). His work aims to advance the understanding of these sensors and the MEG technique, as well as to conduct exploratory measurements in adult subjects exposed to magnetic stimuli in the lower limbs.
