3
Q

When are EEG’s often used?

A

By clinicians as a diagnostic tool as unusual patterns of activity indicate neurological abnormalities like epilepsy, tumours and disorders of sleep

What can EEG technology do today?

A

Accurately detect brain activity at a resolution of a single millisecond

A

Pinpointing the exact source of neural activity

8
Q

What do EEG’s not allow researchers to do?
