Link between Brain and Face Shape
3D images of faces were analyzed and linked several data points on them to their genetic information. This was done to find a correlation. Magnetic Resonance Imaging (MRI) were obtained from 19,644 healthy people; this information was found in the UK Biobank. 472 genomic regions that influences brain shape were discovered. Out of the 472, 76 are also associated with face shape; this large overlap indicated the correlation between face and brain shape. Also, 351 of those regions were never reported before.
The development of the face and brain are coordinated during embryogenesis; According to the study, "genetic signals that influence both brain and face shape are enriched in the regions of the genome that regulate gene activity during embryogenesis, either in facial progenitor cells or in the developing brain."
