Example of a sample subject of the oxygenation changes Δ[O 2 Hb] and Δ[HHb] (μmol/l) from rest (30 s) to stimulation (20 s) period in each of the four conditions Observation (O), Imagery (MI), Observation & Imagery (O&MI) and Imitation (IM). Stimulation on- and offset is indicated by the dotted lines.
