Signal-to-noise ratio of event-related fields in on-scalp and off-scalp MEG

Mainak Jas, Teppei Matsubara, Abbas Sohrabpour, Padmavathi Sundaram, Maria Mody, Seppo P. Ahlfors

The paper compares signal-to-noise ratio (SNR) of MEG signals from on-scalp and off-scalp sensors, finding that OPMs offer better SNR for superficial sources and smaller heads.

Quantifying Cerebellar Signal Detectability in MEG and EEG in Epilepsy Using Anatomically Informed Source Modeling

Teppei Matsubara, Abbas Sohrabpour, Seppo P. Ahlfors, Mainak Jas, John G. Samuelsson, Padmavathi Sundaram, Steven M. Stufflebeam

This paper quantifies cerebellar signal detectability in MEG and EEG for epilepsy using anatomically informed source modeling, finding that depth and geometry, not proximity, primarily affect signal-to-noise ratio.
