Computational head and brain volume conductor modeling is a practical and non-invasive method to investigate neuroelectrical activity in the brain. Anatomical structures included in a model affect the flow of volume currents and the resulting scalp surface potentials. The influence of different tissues within the head on scalp surface potentials was investigated by constructing five highly detailed, realistic head models from segmented and processed Visible Human Man digital images.

- Volume conductor head models include thin tissue layers, like cerebrospinal fluid (CSF) and six cortical layers, which have different conductivity that affects electrical currents.
- The CSF interacts with the skull's shunting behavior, impacting how electrical signals are conducted and measured in the brain.
- Understanding the role of these conductive layers is critical for improving the sensitivity of bipolar electroencephalography (EEG) measurements, prompting recommendations to include these layers in head models.
