Generation of grayscale isochronal maps from Ca²⁺ transient array maps of FIC and control cat bladder strips (A). Ca²⁺ transient maps (B) were analyzed using cross-correlation analysis by manually selecting reference channel with earliest transient, to which all other channels were correlated. Note windowed Ca²⁺ transient, reference trace and maximal correlation (C). Grayscale isochronal maps were generated to represent pattern of Ca²⁺ spread and conduction delays for each bladder strip (D).
