NIRS signals and VMR pattern for subject B – 1st test. Time course of the O₂Hb and CO₂Hb concentration signals for subject B (post-stroke subject) during BH (left panel) and bidimensional VMR pattern (right panel). Data are realtive to the first test, i.e. before the subject underwent therapy. The NIRS signals reveal the absence of vasoreactivity; the 2D pattern shows no functional organization.
