Fig. 7.

Pre and postmotion correction. The figure depicts example channel before and after each motion processing technique is applied. The time series plotted is optical density data. The solid line shows the 690-nm wavelength, whereas the 830-nm wavelength is depicted by the dotted lines. The shaded areas reflect motion artifacts, color coded to reflect each channel. Vertical lines depict the onset of a trial (i.e., time point 0).
