Acknowledgements

Most of the research reported in this book, carried out by Dr Birbaumer and his team at his laboratory in Tübingen — insofar as it was published in specialist journals — was funded by the German Research Foundation (DFG). Our thanks go to the DFG and its highly competent specialist staff for that support, in particular Dr Anne Brüggemann, Dr Theodora Hogenkamp, Dr Manfred Niessen, and Dr Manfred Zimmermann.
