Nervous system would not exist without the human brain. Most neurons send signals via their axons, although some types are capable of dendrite-to-dendrite communication. (In fact, the types of neurons called amacrine cells have no axons, and communicate only via their dendrites.) Neural signals propagate along an axon in the form of electrochemical waves called action potentials, which produce cell-to-cell signals at points where axon terminals make synaptic contact with other cells. Synapses may be electrical or chemical. Electrical synapses make direct electrical connections between neurons, but chemical synapses are much more common, and much more diverse in function.

Pinky and the Brain (voiced by Maurice LaMarche). In "What Ever Happened to Baby Brain", Brain actually crosses paths, who is working as a busboy in a hollywood restaurant, they find themselves inadvertently yelling in unison, "Things will be different when I take over the world!" In "Project B.R.A.I.N." Brain's name is the backronym for the eponymous project: "Biological Recombinant Algorithmic Intelligence Nexus". His tail is angular and bent —he often uses it to pick the lock of the cage—and his head is large and wide, housing his abnormally large brain. He is highly intelligent and develops complex plans for global domination using politics,
