Appendix 1—figure 1. Examples of global variance of the temporal derivative (GVTD) time-traces for a low-motion and a high-motion spoken word recognition high-density diffuse optical tomography (HD-DOT) data.

The red lines indicate the GVTD threshold of ${\displaystyle \stackrel{\sim }{\kappa }+10{\sigma }_{\mathrm{L}}}$ of each run.
