In order to reconcile the advantages of the classical dipole model and minimum norm imaging techniques, higherorder parametric source models based on multipolar expansions of the source have been suggested. We evaluate the ability of dipolar and multipolar MEG source estimation frameworks to localize spatially extended patches of cortical activity. The results show the performance of the differ...
We developed a multichannel system based on superconducting quantum interference devices (SQUIDs) for magnetoencephalography measurements. Our system consists of 163 fully-integrated SQUID magnetometers, 154 channels and 9 references, and all of the operations are performed inside a magnetically-shielded room. The system exhibits a magnetic field noise spectral density of approximatively 5 fT/H...

Stacie and Meg—juniors at Atlas High School—soon must submit their course requests for next year. They have completed 3 years of science as mandated by the school system and must decide whether to take additional courses. Physics is an option, and although it is not required they believe that taking it may help with college admission. To date they have received similar grades (As and Bs) in sci...
