Your brain waves have been measured in order to detect the origins of seizures.

The brain is made up of several areas. For example, the cerebrum is used to think and plan actions. In the cerebellum, movements are initialized and coordinated. The brain stem is responsible for various unconscious tasks such as breathing. The brain stem passes into the spinal cord.

Many of the brain’s processes involve mild electrical currents flowing to the nerve cells. Some of these currents can be measured in the scalp. To take the measurements, various metal plates are laid on the scalp. These are used to test different parts of the brain.

The brain waves are represented as lines or waves on a screen or on paper. If a cramp attack is coming from part of the brain, the lines or waves there may look different to usual.
