Brain

The brain is a pinkish-grey, wrinkled organ that fills the skull — looking, for all the world, like a huge walnut. It is hard to believe, from its appearance, that this ugly lump of jelly contains the mechanisms of thought, perception, will, and consciousness, that it is the seat of our personality. Its 100,000 million nerve cells, each with an average of 100,00 connections from other neurons, makes the human brain the most complicated and least understood object in the known universe. The vertebrate brain is the large anterior portion of the central nervous system . The "cranial vault" of the skull encases the brain in most vertebrates. In invertebrates, the enlarged and specialized anterior ganglion of the central nervous system is often referred to as a brain, although not all scientists regard it as a true brain.

Cerebral palsy

Cerebral palsy (CP) is a disorder that affects muscle tone, movement, and motor skills (the ability to move in a coordinated and purposeful way). CP is usually caused by brain damage that occurs before or during a child's birth, or during the first 3 to 5 years of a child's life.
The brain damage that leads to cerebral palsy can also lead to other health issues, including vision, hearing, and speech problems, and learning disabilities.
There is no cure for CP, but treatment, therapy, special equipment, and, in some cases, surgery can help a child who is living with the condition.
