 Hemisphere Dominance of Brain Function—Which Functions Are Lateralized and Why?

This chapter argues for the investigation of the hemisphere dominances of brain functions rather than structural, cellular, and molecular asymmetries in brains. Although the latter are certainly neural bases of perceptual and behavioral asymmetries generated in the brain, the relationships are largely unclear and most probably complicated in details. Such an approach has both an evolutionary perspective, asking for the common origin and advantages of hemisphere specializations of vertebrate brains, and a perspective of genetic and physiological mechanisms responsible for the realization of hemisphere specializations of certain kinds.

Keywords: brain regions; hemisphere; brain functions; dominances; molecular asymmetries; evolutionary perspective
