Abstract
A stimulating section applies stimulation to a living body. A first lead electrode and a second lead electrode are attached on the living body. A first amplifier circuit amplifies potential difference that is evoked between the first lead electrode and the second lead electrode due to the stimulation. A first switch cancels electrical connection between the first amplifier circuit and each of the first lead electrode and the second lead electrode at least while the stimulation is applied. A high-pass filter includes a capacitor (C) and filters a frequency component of an output from the first amplifier circuit that is no less than a predetermined value. A second amplifier circuit amplifies the output from the first amplifier circuit. A second switch stops charging/discharging of the capacitor (C) and decreases a gain of the second amplifier circuit at least while the first switch cancels the electrical connection.
