Explanation:

EEGs (electroencephalograms) are used to measure the electrical activity of the brain, which is manifested as brain waves. Brain patterns are a more general - term and mental capabilities are not directly measured by EEGs. Electrical activity is too broad a term in this context as EEGs specifically measure brain - related electrical activity in the form of brain waves.
