Extensive tests of the nervous system were carried out.

The nervous system includes all the nerves in the body, as well as the brain and the spinal cord. The nerves run from the brain and spinal cord into the body. They convey information in the body. The brain is located inside the head. It receives, processes and stores sensory impressions. The brain controls movements and various physical functions. The spinal cord is located in the spinal column. The spinal cord is made up of nerve fibers. The brain uses the nerve fibers to exchange information with the organs, skin and muscles.

To examine the nervous system, an MRI of the head, among other things, was carried out. An MRI scan involves creating disc-shaped images of the inside of the body. The scan involves the use of very large magnets.

Brainwaves were also measured. 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. The brain waves are then represented as lines or waves on a screen or on paper. This allows different areas of the brain to be examined.

Cerebrospinal fluid was also taken and examined. Cerebrospinal fluid is a clear fluid that is formed in the brain. There are cavities with cerebrospinal fluid in the brain, around the brain and around the spinal cord. Among other things, the cerebrospinal fluid cushions the brain and spinal cord during knocks and also nourishes the brain cells. The procedure involves inserting a needle into the cerebrospinal space at the bottom of the back between two vertebrae of the spine. A few drops of the cerebrospinal fluid can be collected through the needle.

The cerebrospinal fluid and other samples from the body can be examined with special methods in a laboratory. These samples can be tissue, blood or other bodily fluids. An investigation can be undertaken, for example, to see whether there are pathogens in the samples or whether the quantity of certain substances has changed.

An investigation was also undertaken to see whether the genetic information had altered. This may be the case with certain congenital diseases. Somatic cells usually hold a complete blueprint of your body. This blueprint consists of genetic information. The genetic information is encrypted in the chromosomes. In humans, somatic cells usually have 23 pairs of chromosome, so 46 chromosomes in all. Changes in genetic information can be identified through special tests of blood samples.
