Summary
This paper investigates whether the extracellular space in the brain acts as a resistive or non-resistive medium by comparing the frequency scaling of simultaneous EEG and MEG recordings. The study concludes that significant differences in scaling between the two signals suggest the extracellular medium is globally non-resistive, a finding that challenges standard simplified models used in source localization and neural field calculations.
