Links- oder Rechtshänder? – Die molekularen Grundlagen der Händigkeit

Handedness is one of the most prominent functional hemispheric asymmetries. Initially thought to be determined by a single gene, molecular genetic studies have shown that it is influenced by multiple genes. Recent research indicates that epigenetic regulation induces asymmetrical gene expression in the embryonic spinal cord, potentially leading to motor asymmetries. An integration of multiple genetic, epigenetic, and environmental factors is essential to fully comprehend handedness ontogenesis.
