Figure 3.
The performance of the three methods (rows) when noise with different structure (colored lines) is added to the data with a long ITI. The ITIs were generated using an exponential distribution with ITImean = 10 seconds, ITImin = 1 s, TR = 1 s and the grid size equal to TR. The long ITImean increases the impact of the noise autocorrelation on the HRF estimates.
