¥ 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
