I am reviewing my fmri experimental desing (I model using hrf and TR=3
sec.). Specifically, I am interested to understand which kind of information
I can obtain from the figure 'BASIS SET AND PERISTIMULUS SAMPLING HRF'. How
should I interpret the green sampling points? Does the zero value correspond
to the stimulus onset? Which values are reported on x and y axes?
I know that a precise reply to these questions is time-consuming so I
appreciate if you could point me towards some references in which such
issues are dealt.
Many thanks in advance.
