Experiment: Three human volunteers were exposed to different sounds during sleep. Brain wave patterns were monitored.Observation: Sudden loud sounds triggered a sharp spike in brain wave activity, even in deep sleep.Question: What conclusion is most appropriate?
Correct answer: D. Auditory stimuli can affect brain activity even during unconsciousness.
- A. The brain is inactive during sleep.
- B. Sound cannot penetrate sleep states.
- C. Only light affects brain waves.
- D. Auditory stimuli can affect brain activity even during unconsciousness.
Explanation
The correct answer is option D. The experiment clearly demonstrated that sudden loud sounds caused a sharp spike in brain wave activity, even in deep sleep. This suggests that auditory stimuli can impact brain activity during unconsciousness. The other options are incorrect because they do not align with the specific observations and conclusions drawn from the experiment.
