The aim of this study is to explore the possibility of correlating hemodynamic changes and neural activities in the brain by using an integrated system combining Near Infrared Spectroscopy (NIRS) and electroencephalographic activity (EEG). We present brain hemodynamic changes and EEG recordings obtained from four volunteers during the performance of two different sequential thumb-finger opposition tasks, with and without a related mental activity. The optical and electrical signals were recorded simultaneously on the subject forehead. The coupling of the two systems could be useful to demonstrate correlation between cognitive paradigms and hemodynamic signals.

Abstract
The aim of this study is to explore the possibility of correlating hemodynamic changes and neural activities in the brain by using an integrated system combining Near Infrared Spectroscopy (NIRS) and electroencephalographic activity (EEG). We present brain hemodynamic changes and EEG recordings obtained from four volunteers during the performance of two different sequential thumb-finger opposition tasks, with and without a related mental activity. The optical and electrical signals were recorded simultaneously on the subject forehead. The coupling of the two systems could be useful to demonstrate correlation between cognitive paradigms and hemodynamic signals.
