TL;DR: A new online ARX model based tracking method allows continuous assessment of the transient coupling between the electrophysiological (EEG) and the hemodynamic (NIRS) signals representing resting-state spontaneous brain activation during anodal tDCS.

TL;DR: It was concluded that the anodal tDCS can perturb the local neural and the vascular activity (via NVC) which can be used for assessing regional NVC functionality where confirmatory clinical studies are required.

TL;DR: It is proposed to combine NIRS-EEG/tDCS joint-imaging with corticospinal excitability investigation in a single study to confirm the finding that post-tDCS changes in the mean rSO2 from baseline mostly correlated with the corresponding post- tDCS change in log-transformed mean-power of EEG.

TL;DR: It is demonstrated that temporal artery tap may be used to better identify systemic interference using near-infrared spectroscopy using this short-separation NIRS, and proposed that anterior temporal arteryTap technique presented in this paper may be able to classify carotid stenosis, externalCarotid artery stenosis and internal carotids patients using the laterality in the hemodynamic response evoked by anodal tDCS both at the brain as well as at the superficial layers.

TL;DR: A 4-channel continuous wave NIRS combined with tDCS in an FPGA-based hardware that captured the hemodynamic changes in the frontal cortex of the brain, as a measure of CVR, before and after anodal tDCS is presented.
