Table 3.

Fast (D_fast) and slow (D_slow) diffusion coefficients referenced in the literature [7,10,42–44] and estimated using the bi-exponential decay model. Units for D_fast, and D_slow, are expressed in [10⁻³ mm² s⁻¹]. The ranges represent minimum and maximum values. For comparison, data extracted from the present experiment are also reported. GM, grey matter; WM, white matter.

human GM (in vivo)	0.25–0.51	0.93–1.74	0.19–0.47
rat GM (in vivo)	0.17–0.33	0.82–0.9	0.17–0.26
Xenopus laevis oocytes	0.11	1.06	0.16
