Sensory maps and brain development the midbrain auditory nucleus had receptive fields independent of nature and intensity of the sound. Roger Sperry proposed a chemical gradient model for eye rotation and for neuronal wiring diagram. Retinal neurons and target cells had identification tags in the form of chemical gradients so that the projection of neurons would be orderly. For a topographic map of the visual world, the map first forms during neural development via molecular signals, such as chemospecific matching between molecular gradients. The molecular basis of sensory maps and brain development is a field that is being actively explored. The most recent work has
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,
