question 194

Multiple Choice

• C) Yes, because an EOG would tell you if your eyes were open.
• D) Yes, because the EOG would measure jerky eye movements that characterize one type of sleep, called REM sleep.
• E) No, because your breathing rate is also a factor and would not be monitored by an EOG.
