Notes:
For accurate and reliable EEG recording. electrode resistances must be kept relatively low and constant. To ensure that these conditions are met, a fixing agent, collodian, is usually used to fix the electrodes firmly to the scalp. Collodian, however, produces many unwanted side effects. A “double-cllar” method of electrode placement is described whereby electrodes may be firmly fixed to the scalp without the use of collodian. This technique is both faster and less troublesome than the use of collodian. Using this technique, electrode resistances at vertex and occiput were well below generally acceptable criteria (averaging under 5000 ohms) and there was no significant increase in resistance at either placement following nearly 2 hrs of continuous EEG recordings. It is concluded that, under certain laboratory conditions, the “double-collar” method of electrode preparation and placement is superior to the use of collodian.
