Abstract
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.

Wie funktioniert das Gehirn? Die Arbeitsgruppe Biopsychologie untersucht die neuronalen Grundlagen des Verhaltens und kognitiver Prozesse. Wir charakterisieren die Neurophysiologie psychologischer Phänomene anhand von Versuchspersonen, hirnverletzten Patienten und im Tiermodell. Die Arbeitsschwerpunkte unserer Forschung sind die Entstehung und Physiologie funktioneller Hirnasymmetrien, die neuronalen Grundlagen von Lernen und Gedächtnis sowie die Frage nach der Evolution von Gehirn und Denken.
