Genes influence different brain structures and function. These in turn explain differences in behavior. Analyzing all three aspects at once is a challenge – but now succeeded.

Intelligence is partly genetically determined. There are studies showing that certain gene variations are linked to better performance in intelligence tests. Other studies show that different brain characteristics, such as efficient networking, are linked to intelligence. Now, for the first time, researchers have studied all three parameters – genes, different brain characteristics and behavior – simultaneously. Using gene analyses, magnetic resonance imaging and intelligence tests, the team demonstrated which brain traits form the link between genes and behavior.

The results are described by a team led by Dorothea Metzen from the Biopsychology Unit at Ruhr-Universität Bochum and Dr. Erhan Genç, formerly at Ruhr-Universität, now at the Leibniz Institute for Human Factors Research in Dortmund (IfADo), in the journal “Human Brain Mapping,” published online April 4, 2023.
