Scientific background

Voluntary control of metabolic function of sub-cortical and cortical areas were successfully tested and published by our group in healthy subjects and in psycho­pathological conditions (psychopathy and anxiety disorders). Subjects or patients observe changes of BOLD-responses in circumscribed areas of their own brain measured with functional magnetic resonance imaging (fMRI) and are rewarded with feedback for the changes in BOLD achieved. People are able to learn to up- or down-regulate specific brain areas or to modulate the connectivity between selected brain regions. Because fMRI is costly, a cheap and portable Near-Infrared-Spectroscopy (NIRS) system was developed by our group together with a Japanese and Singapore-located group and it was demonstrated that regulation of local cortical blood flow is possible analogous to the fMRI-BMI system.


Objectives

To demonstrate long-lasting and area-specific effects of fMRI-BMI connectivity training and NIRS-BMI connectivity training on behavior and symptoms of attention deficit disorder (ADHD), psychopathy and stroke.
