¥ FMRI Stimulus¨Signal connection and noise statistics are both poorly characterized
¥ Result:
there is no ÒbestÓ way to analyze FMRI time series data: there are
only ÒreasonableÓ analysis methods
¥ To deal
with data, must make some assumptions about the signal and
noise
¥ Assumptions
will be wrong, but must do something
¥ Different
kinds of experiments require different kinds of analyses
H Since signal models and questions you
ask about the signal will vary
H It is important to understand
what is going on, so you can select and
evaluate ÒreasonableÓ analyses
