The brain is a complex organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It contains billions of nerve cells that are connected by synapses to other cells and can send a train of signal pulses throughout the body.he brain is a complex organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.

Jellyfish, comb jellies, and related animals have diffuse nerve nets rather than a central nervous system. In most jellyfish the nerve net is spread more or less evenly across the body; in comb jellies it is concentrated near the mouth.he evolution of nervous systems dates back to the first development of nervous systems in animals (or metazoans). Neurons developed as specialized electrical signaling cells in multicellular animals, adapting the mechanism of action potentials present in motile single-celled and colonial eukaryotes.
