Electroencephalography
Electroencephalography (also known as EEG) was a medical test for measuring the electrical activity of the brain, such as theta waves.

In 2153, an EEG was performed as part of the collection of biometric data about a Borg drone by using electrode pads. The data was submitted to a computer monitor. ()

In 2365, a biobed performed an EEG scan on Commander William T. Riker. ()

In 2367, Nurse Ogawa monitored Riker's EEG while he was having the Trill symbiont Odan transplanted into his body. ()
