Spatiotemporal activities in S1 cortex. a The dashed white circle outlines the maximal spatial boundaries of optical activity in the S1 cortex area. A bold blue line is used for spatiotemporal analysis in the S1 region, the region of interest (ROI) borderline of neural excitation area; scale bar = 800 μm). b Spatiotemporal map of the optical activity during data acquisition. Each vertical white line represents the time point of electrical stimulation of the hind paw of nerve-injured rat. Before EA stimulation (Pre-EA), regions of neural activity were presented by distinctive fluorescence signals during recording time. In contrast, after EA stimulation, neural activity immediately decreased and then time-dependently recovered until 150 min
