Dense-Array Electroencephalography (dEEG)
The dense array electroencephalography (dEEG) is a recording of brain activity.
Brain cells continually send messages to each other that can be picked up as small electrical impulses on the scalp. The process of picking up and recording the impulses is known as an EEG. This procedure tracks and records brain wave patterns.
The Cheatham Lab uses the Dense-Array Electroencephalography (dEEG).
Your head is fitted with a stretchy net that has been soaked in a warm saline solution. The sponges on this net touch your scalp and will enable us to record the electrical activity generated by your brain. After the net is in place, a few moments will be spent getting the cameras adjusted to track your eye movements. Then you will sit in front of a computer screen and watch pictures on the screen. While you are watching these pictures, we will be recording the brain activity (electrical impulses) at the scalp as well as the information from the cameras.
The dEEG technique can monitor and interpret the brain’s electrical activity in infants through the elderly when combined with computer-based activities. The dEEG tells us when the brain is active and how active it is.
In the video below, Independent Tribune reporter Ben McNeely's brain waves are measured by Dr. Cheatham. During the test, McNeely pushes a button when he sees a certain shape appear on a computer screen while a electrode sensor net reads his brain activity.
