Handedness, language areas and neuropsychiatric diseases: insights from brain imaging and genetics
Wiberg A., Ng M., Al Omran Y., Alfaro-Almagro F., McCarthy P., Marchini J., Bennett DL., Smith S., Douaud G., Furniss D.
<jats:p>The brain signature and genetic basis of handedness are unclear. Wiberg et al. show that left-handers have higher functional connectivity between language networks, and identify four genomic regions associated with handedness. Variants within these regions appear, by influencing brain architecture, to predispose both to left-handedness and to certain neuropsychiatric diseases.</jats:p>
