Figure 1: A) PAUS setup. The PAUS probe is placed on a gel pad to allow for PAUS-guided KCI stimulation in the imaging plane. ECoG was used to validate SDs detection. B) and C) show examples of PAUS imaging of blood oxygenation (sO2) responses to SDs induced with KCI. Notice in B the development of 4 consecutive SDs. In C the placement of 5 ROIs is indicated. After stimulation the development of 2 SDs is detected in ROIs-1-3, while in ROI-5 only 1 SDs was detected.
