Electroencephalography (EEG) records brain waves, but it doesn't read minds or measure IQs. Instead, it's used to detect the level of electrical activity in the brain. Your brain cells communicate by electrical impulses, and an EEG measures and records these electrical impulses to detect anything abnormal.
An EEG measures primarily grey matter or higher brain function. The largest part of the brain is comprised of the cerebrum, which is split into right and left hemispheres. The cerebrum controls voluntary actions, thought, speech, and memory. In humans, the cerebrum comprises most of the brain, while in other mammals it's relatively small. This allows us to perform much more complicated actions than other species can.
The outer layer of the cerebrum, called the cerebral cortex, is responsible for most higher brain functions such as thought, reasoning, memory, and voluntary muscle movement. The cerebral cortex is mostly made up of neurons, which are nerve cells that carry message
