Brain structural complexity and consciousness

Structure shapes function. Understanding what is structurally special about the brain that allows it to generate consciousness remains a fundamental scientific challenge. Recently, advances in imaging techniques have made possible measure structure of human brain, from morphology neurons and neuronal connections gross anatomy regions, in-vivo non-invasively. Using advanced techniques, was discovered structural diversity between topology connections, as opposed sheer number or are key consciousness. When high follow modular topology, will become functionally differentiable integrable with one another. The levels differentiation integration, turn, enable produce richest conscious experiences smallest connections. Consequently, across individuals, those smaller volume but higher tend richer than larger lower diversity. Moreover, within reduction if accompanied by an increase diversity, result experiences, vice versa. These findings suggest having not necessarily beneficial for consciousness; contrast, optimal architecture where generated at minimal cost biological material, physical space, metabolic energy.
