From: Characterization of the hemodynamic response function in white matter tracts for event-related fMRI
Average TTPs of WM tracts and their connecting GM clusters. Average TPP of one WM tract was displayed in the center of each panel with the average TTP of its connecting GM clusters on either side. The y-axis is the TTP (seconds). Points are laid over a 1.96 SEM (95% confidence interval) in red, a 1 SD in blue and a center line that denotes the median. 9 of 11 tracts showed significantly longer time (P < 0.05, t-test) to reach the peak in comparison with their connecting GM clusters.
