Spatial correlation analysis (620 nm data). (A) Sample IOM from one ferret (Ferret 1). (B, C) Images of the percent change from the mean OIS signal at the time point of maximal spatial correlation to the IOM for evoked and resting conditions, respectively. The red arrows indicate patches reflecting the structure of orientation domains that are common in all three images. (D) Histograms of the values of spatial correlation to the IOMs for all images and orientations analyzed in evoked (top panel) and resting states (middle panel) from this animal are shown. Similarly, the histogram of spatial correlation values of all resting state images to pseudorandom IOMs is shown in the bottom panel. Difference images that resemble the IOM will produce relatively high correlation coefficients and yield overall histograms with wider spread. (E) Grouped results from all animals. IOM, iso-orientation map.
