Quizplus · Accepted Answer

The study used fMRI to measure brain activity, and found that attention directed to one side of the display caused changes in brain activity even without actual eye movements, supporting option C. Option A is incorrect because the study found changes in brain activity without actual eye movements. Option B is also incorrect because the study did not use single neuron recordings to measure brain activity.
