Acknowledgements This research is part of the project "Wavelets and their applications", funded by the Dutch National Science Foundation (NWO), project no. 613.006.570. ...
The HRF extraction method described here is data-driven instead of model-driven. ...
It is based on Fourier-wavelet regularised deconvolution, ForWaRD for short, developed originally for denoising and deblurring of images [17] . ...

In order to identify the visual cortex we performed a standard SPM analysis of the mean ISI=3 session (60s high pass filter, haemodynamic response function (HRF) low-pass filter). ...
The region thus identified was used to extract mean time courses in the other ISI sessions. ...
We use a wavelet basis function set (e.g. Daubechies 4, (2)) to generate the design matrix for the observation level. ...
