Explanation:

For the first question: EEG is the primary tool used to study sleep by measuring brain wave activity, which is critical for identifying sleep stages. Other scans like MRI, CT, and MEG are not standard for routine sleep studies.
For the second question: MEG (Magnetoencephalography) measures brain electrical activity by detecting the magnetic fields generated by that activity, matching the description provided.

Answer:

1. Electroencephalograph (EEG)
2. MEG
