Question

What is the signal amplitude of EEG?

(a) 2-200 µV

(b) 2-200mV

(c) 2-2000 µV

(d) 2-2000mV

Answer 1

Right answer is (a) 2-200 µV

Explanation: The signal amplitude of EEG is between 2-200 µV. It is very small and requires special type of electrodes namely scalp electrodes. EEGs are difficult to capture because its signal range in very small and motion artifacts are much greater.
