 In a three-shell EEG volume conduction model (either spherical or realistic) the conductivity ratio'​s of 1, 1/80, 1 are commonly specified for scalp, skull and brain. The proper conductivities are then 0.3300, 0.0042 and 0.3300 S/m respectively. For a four-shell EEG volume conduction model the conductivities of scalp, skull, CSF and brain are commonly specified as 0.3300, 0.0042, 1.0000 and 0.3300 S/m.  In a three-shell EEG volume conduction model (either spherical or realistic) the conductivity ratio'​s of 1, 1/80, 1 are commonly specified for scalp, skull and brain.
