EEG Tests – Three Unexpected Things EEGs Do

EEG Tests

What EEGs Do

The human brain is a complex organ, maybe the most complex organ we know of. It’s difficult to glean much information about the inner workings of the brain, but that doesn’t stop us from trying.

Electroencephalography (EEG) is one of the most versatile tests of brain activity. Electrodes are placed on the patient’s head in various locations, measuring electrical neural impulses from different angles. Now, you might be wondering, “Why do this? What can you do with EEG data?” The answer is, “more than you think.” While EEGs are primarily used for medical testing, it’s a surprisingly versatile test.

Three Unexpected Uses of Electroencephalography

1. Brain Computer Interface (BCI)

EEGs work fast enough that you can use them as an input for computers. EEGs have been used to control music, fly a helicopter, and steer a wheelchair. Researchers are constantly improving the technology and coming up with new uses for it. As companies continue to make more cost-efficient EEGs and increase fidelity, more and more people will have the chance to control computer systems with their brains, with ever greater precision.

2. Detect Boredom

Let’s say your friend is telling you a story and you say it’s interesting, but you really couldn’t care less about a sandwich they ate last week having too much mayo. If they are telling you the story while taking an EEG test, they will see right through your white lie, because EEGs can accurately detect level of engagement or boredom.

3. Help Train The Brain

Neurofeedback involves looking at (or hearing, or sensing in some other way) one’s EEG data while it’s happening and intentionally making changes in one’s brainwaves based on that real-time feedback. This can be a very useful tool for people coping with stress, treating anxiety, sleep disorders, PTSD, and other conditions, as well as improving focus and many other areas of mental activity.
