We measured inversion recovery prepared diffusion signal for grey matter. We found that the mean diffusivity (MD) in grey matter drops significantly for TIs higher than the nulling TI. MD in GM dropped from around 0.8×10-3 mm2/s before the null point to around 0.6×10-3 mm2/s immediately after the null point. Our findings suggest that the neocortical gray matter could be characterized using a two dimensional T1-diffusion correlation measurement.
