encephalography

The spatial resolution of the two encephalography technologies is notoriously imprecise, however, because the recordings are made through the scalp.

Researchers tested this hypothesis by inducing yawning in human subjects and then observing brain activity with encephalography as they yawned.

The mentation pictures we got by encephalography compare very favorably with those of any human child of ten or twelve years old, and so does their learning and puzzle-solving ability.
