Lavon is taking part in an experiment in the cognitive neuroscience lab on campus. silently, he reads rapid sequences of words flashed on a computer screen. simultaneously, the electrical activity of his brain is recorded through skull electrodes. the brain scanning technique used in this study is:

The brain scanning technique used in this study is "EEG."

Electroencephalography (EEG) is the measurement of the electrical movement of the brain by recording from cathodes set on the scalp. The subsequent follows are known as an electroencephalogram (EEG) and speak to an electrical signal from countless neurons.  

EEGs are oftentimes utilized in experimentation in light of the fact that the procedure is non-obtrusive to the exploration subject. The EEG is fit for recognizing changes in electrical movement in the cerebrum on a millisecond-level. It is one of only a few techniques accessible that has such high temporal resolution.
