Please answer by selecting exactly one option: A, B, C, or D.\n\nQuestion: Which statement about delta activity is the most cautious?\nA. Any delta activity necessarily indicates deep sleep.\nB. Delta is always an eye-movement artifact.\nC. Delta can reflect brain activity, but it can also be affected by slow drift, sweat, movement, and other low-frequency artifacts.\nD. Delta appears only in the occipital posterior dominant rhythm." | |
