Abstract

The gross weight or volume of an adult mammalian brain is a natural biological statistic that estimates fundamental between-species parameters of structure and function. Among the relationships that have been discovered, the best established and most important is between brain weight and the surface area of the entire cerebral cortex. It shows that brain size may be used to estimate the total neural information processing capacity of a species. Other quantitative features of the brain that are related to brain size include the number of cortical neurons, average cortical thickness, average neuron density, extent of axodendritic arborization, neuron/glial ratios, and various neurochemical measures.
