    Dear Editor,
    We would like to submit the letter below as eLetter to the Article
    Christian I. Penaloza* and Shuichi Nishio, BMI control of a third arm for multitasking, Science Robotics 25 Jul 2018: Vol. 3, Issue 20, eaat1228, DOI: 10.1126/scirobotics.aat1228
    We have sent the authors our concerns and questions directly but the response we have received from them did not address the issues we found in this paper as described below.
    We believe that our eLetter contains important information for readers to understand the validity of the findings reported by Penalzo and Nishio and should therefore be published as eLetter alongside the original article.
    With kind regards
    Carsten Mehring and Etienne Burdet

    =====
    There have been several recent attempts to develop approaches for human movement augmentation, for example autonomously or EMG controlled supernumerary limbs [1,2] as well as Brain or Body Computer Interfaces which can be controlled simultaneously and in coordination with movements of the natural limbs [3-7]. Christian Penaloza and Shuichi Nishio report in the Vol. 3, Issue 20 of Science Robotics on the EEG control of a supernumerary arm and claim that their system may enhance human capabilities f...
