Abstract

The human ability to live according to learned, shared rules of behavior requires cortical functions. Is the limbic system also necessary for culture or are its functions opposed to it, requiring cortical inhibition? The sizes of monkey and ape neocortical and major limbic structures scale with brain weight, but the neocortex expands more (has a steeper exponent) than limbic structures. As the human brain evolved it did not deviate from the scaling relationships found in nonhuman anthropoids. This evidence for conservation in scaling supports the idea that limbic functions are necessary for human symbolism and culture.
