Impact of time-lagged rCBF on ${\mathrm{rCMRO}}_2$ with different time lags (0.8 s, 1.6 s, 2.2 s, 2.4 s): (a) amount of information shared between rCBF and ${\mathrm{rCMRO}}_2$ measured by MI, (b) TE indicates the amount of information exchanged from rCBF to ${\mathrm{rCMRO}}_2$ and vice versa with different time lags, (c) DI indicates the dominant direction of the transfer, the negative sign indicates the dominance of ${\mathrm{rCMRO}}_2$ over rCBF and vice versa.
