Abstract:
Nowadays left-handedness as separate problem is the subject of the attention of medicine, neurobiology, psychology and other sciences. This fact is explained by big amount of theoretic paradigmas that are based on research of right-handed people. In spite of cardinal turn to the problem of left-handedness in different fields in the last decade but we can’t name any solved problem connected with this phenomenon. Functional asymmetry of hemispheres expands the possibilities of the brain significantly, makes it more perfective. However the phenomenon of asymmetry is not so simple: some features are typical for one hemisphere only, other for both but in
different way, and all of this has difficult interdependence and interaction.
