    Hi,
    I’ve just converted some monopolar EEG data (in Volts) to CSD using mne.preprocessing.compute_current_source_density, but I am confused about the units of the outcome. I thought the function would return V/m^2, but I get averaged event-related potentials in the magnitude [-.005, .005]. Could you please clarify?(it would also be useful to clarify this in the MNE documentation, unless I missed something)
    Kind Regards

@mservant is it possible that the code uses distances in mm and not m ?

sorry I am not super familiar with this code
