From: Dynamic response of cerebral blood flow to insulin-induced hypoglycemia
(a) Dashed blue curve is an example of time-dependent diffusion coefficient, αDB(t), obtained by fitting the autocorrelation curves measured over time in a single subject. Note that insulin was injected at t = 0. The red curve in (a) was obtained by denoising the data of the blue curve. αDB(t0) is the reference diffusion coefficient and corresponds to the onset of the rise of αDB(t). The curve in (b) was obtained by applying Eq. (4) to the denoised αDB(t) data (i.e., the data of the red curve in a).
