Robust and Unbiased Variance of GLM Coefficients for Misspecified Autocorrelation and Hemodynamic Response Models in fMRI
Figure 1
Convolution of the HRF and the stimulus function for an event-related (a) and a blocked design (b). Stimulus presentation latencies for condition A (solid blue) are indicated with filled circles, and open circles for condition B (dashed red). Parameters of the HRF are taken from [18].
