This strategy is otherwise called profound cerebrum recording [11]. To execute Electroencephalography procurement a gifted individual needs to put cathodes inside the scalp utilizing the medical procedure. As the terminals for the intrusive method are put on the uncovered cerebrum and subsequently, the nature of the sign is far superior to the non-invasive procedure. This kind of intrusive procedure is frequently utilized for serious epileptic patients to distinguish the area of appropriations [12]. Even though this procedure delivers top-notch Electroencephalography signal, here and there scar tissues can develop, which, thusly, make the sign more vulnerable and, in the most noticeably terrible case, the sign may get lost [13]. There are different electrode materials available to measure and record the electroencephalography signal from the brain of the human body. They are listed as follows:

 • Needle Electrodes made of AgCl

 • Needle Electrodes made of Stainless Steel

 • Needle Electrodes made Gold

 • Needle Electrodes made of TiO2.

These electrodes are inserted into the human brain for recording the electroencephalography signal, which causes pain during the test and also the patients feel discomfort during measurements.
