Correlation between live and post mortem skull conductivity measurements.
The skull is a tissue with a widely controversial range of conductivity values. This article correlates live skull conductivity measurements with post mortem conductivity measurements with a scaling factor ranging between 2.5 and 4. The scaling factor is validated by a mathematical model that determines the skull conductivity using saline and cerebrospinal fluid (CSF) conductivities and correlated with published physical live and post mortem skull conductivity measurements which show support for this live-to-post mortem scale factor.
