Your brain waves have been measured.

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. When certain conditions are present, the lines and waves look different to usual.

Your brain waves were recorded using a device that you could wear on your body. This enables the brain waves to be measured over a longer time period.
