Question

the electroencephalogram, or eeg, detects
______ through their electrical output.

• brain tumors
• brain dysfunction
• brain waves

Explanation:

An Electroencephalogram (EEG) records the electrical activity generated by the brain's neurons, which manifests as brain waves. Brain tumors are typically detected via imaging like MRI/CT, and brain dysfunction is a broad condition that an EEG may help assess, but the direct electrical output detected by EEG is brain waves.

Answer:

brain waves
