In conventional scalp EEG the recording is obtained by applying electrodes to the scalp using a conductive gel or paste usually after preparing the scalp area by light abrasion to reduce electrode-scalp impedance. Many systems typically use electrodes which are each attached to an individual wire.

Types of Surface Electrodes (Floating Metal Plate
· The floating electrodes do not contact the human subject directly. They contact the subject via electrolytic paste or jelly. The advantage of this type is the mechanical stability. Ear Clips and Scalp Electrodes. In the measurement of EEG ear clip electrodes are used. Scalp electrodes provide EEG signals easily when placed on bare head.

· The nomenclature in the basic array is consistent with the 10–10-system. High-density scalp EEG arrays (64–256 electrodes) allow source imaging with even sub-lobar precision. This supplementary exam should be requested whenever necessary e.g. search for epileptogenic activity in negative standard EEG or for presurgical evaluation.

These electrodes are applied to the scalp using a conductive gel or paste usually after preparing the scalp area by light abrasion to reduce electrode-scalp impedance. Personal opinion Passive electrodes are the electrodes that I take more time/work to get a good impedance. Sometimes I am not able to get the wished impedance for some electrodes.
