Alpha waves are typically recorded from which part of the head?

• A. Frontal lobe
• B. Occipital lobe
• C. Parietal lobe
• D. Temporal lobe

Answer: (B)

Alpha waves are most prominently recorded from the occipital lobe of the brain. This is primarily because the occipital lobe is the region responsible for visual processing and is known for its high levels of activity during relaxed, awake states with closed eyes. When a person is relaxed but not asleep, alpha activity is predominant in this area, reflecting a calm yet alert state that is often associated with restful wakefulness and the absence of excessive visual stimuli. This phenomenon has been well established in electroencephalography (EEG) studies, which show that alpha waves tend to have their highest amplitude over the occipital regions of the scalp.
