2019 Nature Communications  
Neurotechnology attempts to develop supernumerary limbs, but can the human brain deal with the complexity to control an extra limb and yield advantages from it?  ...  Anatomical MRI of the supernumerary finger (SF) revealed that it is actuated by extra muscles and nerves, and fMRI identified a distinct cortical representation of the SF.  ...  We thank Claudia Clopath, Nicolas Rojas and Stephen Scott for comments on an earlier version of this manuscript and Dmitry Kobak for comments on parts of the analyses.  ...
