The ground is used for common mode rejection. The primary purpose of the ground is to prevent power line noise from interfering with the small biopotential signals of interest. By design, amplifiers should not be affected by large changes in potential at both the active and reference sites. A ground electrode for EEG recordings is often placed on the forehead (but could be placed anywhere else on the body; the location of the ground on the subject is generally irrelevant).
Shock Protection. Grounding means linking an electrical circuit to the ground and works on the principal that the earth is a handy conductor of electricity. The grounding of electrical devices and appliances protects those who handle and use them from electrical shocks and accidents.
