Masalan EEGda delta, tetta, alfa, betta kabi to‘lqinlar bor. Delta to‘lqin 1-3
gersni, tetta to‘lqin 4-7 gersni, alfa to‘lqin 8-13 gersni va betta to‘lqin 14-30 gersni
tashkil qiladi. Bundan tashqari uyquning darajalari farqlanadi:

Bundan tashqari artifaktlar ham mavjud. Agar neyrofiziolog artifaktlarni
farqlay olmasa yoki EEG olish mobaynida juda ko‘p artifaktlar bo‘lsa, patologiyani
o‘tkazib yuborishi mumkun. Ekstraserebral manbalardan kelib chiqqan elektr
potensiallari artifaktlar deyiladi. Artifaktlar fiziologik va nofiziologik bo‘lishi
mumkin. Fiziologik artifaktlarga okular, kardialogik, miogen, glossokinetik,
respirator, terlash, harakat artifaktlari kiradi. Nofiziologikka esa ko‘zning
chayqalishi, til harakati, neyrostimulyator, bosh chayqalishi, ventilyator, psixogen
(epileptik bo‘lmagan), tremor, fokusli yuz harakatlari, elektrod artifaktlar kiradi.
