Brain and quality of experience are important; for example, there is substantial evidence that animals raised in enriched environments have thicker cerebral cortices, indicating a higher density of synaptic connections, than animals whose levels of stimulation are restricted. The functions of the brain depend on the ability of neurons to transmit electrochemical signals to other cells, and their ability to respond appropriately to electrochemical signals received from other cells. The electrical properties of neurons are controlled by a wide variety of biochemical and metabolic processes, most notably the interactions between neurotransmitters and receptors that take place at synapses. Neurotransmitters are chemicals
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,
