Lateralita, leváctví a specializované funkční oblasti mozku

Roč.10,č.2(2019)

Abstrakt

Tato přehledová studie se zaměřuje na fenomén laterality obecně i na její konkrétní formy, což jsou leváctví a asymetrie mozkových hemisfér. Autorka se snaží se tyto pojmy definovat, popsat a vysvětlit případný vztah mezi vedoucí rukou a asymetrií hemisfér, konkrétně specializovaných funkčních oblastí v mozku člověka. Ve studii jsou nastíněny teorie, které řeší otázku, proč lateralita rukou a mozku evolučně vznikla a z jakých důvodů se vyvine u jedince, a to z hlediska genetických příčin i možného vlivů prostředí. Studie následně popisuje leváctví a praváctví v lidské populaci, klasifikaci laterality rukou u člověka a možnosti, jak vedoucí ruku určit.
