Neurosteer monitored two runners, in real time, during the NYC marathon on Nov 3rd. Prof. Steven Laureys, a key figure in the European Human Brain Project, was behind this initiative, which created significant interest in sports and other brain monitoring in extreme physical conditions. The article in DeMorgen describes it (in Dutch; use Google Translate). The full event was streamed live on Facebook. When going over the recording, one can see that Steven was meditating during much of the run (a well-known method to reduce oxygen consumption).
