Laterality, left-handedness and specialized functional areas of the brain

Publication at Faculty of Humanities |

Abstract

he review focuses on the phenomenon of laterality in general and also it focuses on specific forms of laterality that are handed-ness and the asymmetry of brain hemispheres. The author tries to define the terms, describe the phenomena and explain a potential relation-ship between the dominant hand and the asymmetry of brain hemispheres, specifically the asymmetry of specialized functional areas in the human brain.

There are theories presented in the study that try to answer a question why the laterality of hands and brain evolved. Theories about mechanisms of how laterality can develop at an individual level are presented too, both from genetic and environmental points of view.

Study subsequently describes handedness among human population, classification of the laterality of hands and ways how one can tell which hand is the dominant one.
