Fig. 11.

Same experiment as shown in Fig. 10 but with the normalization of autocorrelation functions by C(1, 0), i.e., autocorrelation between 2 neighboring pixels along the fast scanning direction on the image. Such normalization should reduce the influence of the changes in shot noise during the acquisition. As in Fig. 10, the model fit predicts anisotropic diffusion of Alexa-ATP in cardiomyocytes with diffusion coefficients equal to 53 μm²/s in the transverse direction and 86 μm²/s in the longitudinal direction.
