Short latency of neuro-scattering responses relative to neurovascular coupling and their wavelength representatives. The peak times of scattering (neural tissue) and tHb (vascular volume) are plotted individually along with the group mean+/−SEM (a: S1, 1.41+/−0.30 vs 3.41+/−0.21 and b: CP, 1.22+/−0.16 vs 2.96+/−0.44). Paired t-tests between scattering and tHb for both groups, found a significantly faster response in scattering activity than vascular activity (*: p<0.05, **: p<0.001, two-tailed).
