Summary

[edit]
Description
English: Common artifacts in human EEG.

1. Electrooculographic artifact caused by the excitation of eyeball's muscles (related to blinking, for example). Big amplitude, slow, positive wave prominent in frontal electrodes. 2. Electrode's artifact caused by bad contact (and thus bigger impedance) between P3 electrode and skin. 3. Swallowing artifact.

4. Common reference electrode's artifact caused by bad contact between reference electrode and skin. Huge wave similar in all channels.
Українська: Приклади основних типів електроенцефалографічних артефактів.

1. Електроокулографічний артефакт, викликаний активністю окорухових м'язів (наприклад, під час відкривання/закривання очей). Це високоамплітудне позивне повільнне коливання, найбільш виражене у фронтальних відведеннях. 2. Електродний артефакт, викликаний поганим електричним контактом електрода (в даному випадку Р3) зі шкірою, а відтак - великим опором. 3. Ковтальний артефакт.

4. Артефакт, пов'язаний з референтним електродом. Особливістю є те, що артефактна активність є однаково вираженою у всіх каналах ЕЕГ.
