Decorrelation time as a function of fiber tip penetration depth. As the fiber tip penetrates deeper into the brain tissue, the decorrelation time decreases due to the increasing number of scattering events. The error bars indicate the standard error of the mean of the decorrelation times over the 14 total data sets from three mice at each depth.
