‘Mirror twins’ and brain asymmetry

University of Auckland researchers are seeking identical and non-identical twins for a study of brain asymmetry and the genetics of being right or left handed.

About 25% of identical twins are ‘mirror twins’, or twins with opposite handedness. The study will map brain structure and function in volunteers to try to determine if different handedness is associated with mirrored differences in the brain.

It will also look at whether being left or right handed is really due to genetics or whether other factors are at play.
