a
Td, duration of the experiment after MCAO.
b
Correlation coefficient (R2) and statistical significance (P, for the slope difference from zero) of the linear fit.
c
The 23Na MRI slope data were excluded because of the movement in the animal holder assembly.
d
Fit parameters are not shown as lacking statistical significance.
NA = not available.
