Background
|
The brain is the center of the nervous system in all vertebrate and most invertebrate animals. Some primitive animals such as jellyfish and starfish have a decentralized nervous system without a brain, while sponges lack any nervous system at all. In vertebrates the brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, balance, taste, and smell. Alternative Names: Human Brain Tissue Lysate, Brain Lysate, Human Brain Lysate, Normal Human Brain Lysate
