- A couple of tangential facts about the cerebral cortex: First, it is one of the more recent evolutionary developments of the brain, contributing to the complexity of mammal behavior relative to the behavior of older classes of animals like reptiles and amphibians. Second, while the brain is informally referred to as gray matter because the cerebral cortex is the brain’s external surface and this cortical tissue is gray in color, the bulk of the brain is in fact white matter. By and large, the white matter is responsible for carrying information over longer distances than the gray matter, so its neurons have a white-colored, fatty coating that hurries the pace of signal — location:
conduction. A coarse analogy could be to consider neurons in the white matter to act as “highways. ” These high-speed motorways have scant on-ramps or exits, but can transport a signal from one part of the brain to another lickety-split. In contrast, the “local roads” of gray matter facilitate myriad opportunities for interconnection between neurons at the expense of speed. A gross generalization, therefore, is to consider the cerebral cortex—the gray matter—as the part of the brain where the most complex computations happen, affording the animals with the largest proportion of it—such as mammals, particularly the great apes like Homo sapiens— their complex behaviors — location:
