As experienced already in prior competitions not only scientists from the narrow field of BCI compete, but scholars with a broad variety of backgrounds and nationalities. They include high specialists as well as students. The goals of all BCI competitions have always been to challenge with respect to novel paradigms and complex data. We report on the following challenges: (1) asynchronous data, (2) synthetic, (3) multi-class continuous data, (4) session-to-session transfer, (5) directionally modulated MEG, (6) finger movements recorded by ECoG. As after past competitions, our hope is that winning entries may enhance the analysis methods of future BCIs.10aBCI10abrain-computer interface10acompetition1 aTangermann, M1 aMuller, K R1 aAertsen, A1 aBirbaumer, Niels1 aBraun, Christoph1 aBrunner, Clemens1 aLeeb, R1 aMehring, C1 aMiller, K J1 aMueller-Putz, G1 aNolte, G1 aPfurtscheller, G1 aPreissl, H1 aSchalk, Gerwin1 aSchlögl, A1 aVidaurre, C1 aWaldert, S1 aBlankertz, Benjamin  uhttp://www.ncbi.nlm.nih.gov/pubmed/22811657
