The development of positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) as noninvasive methods for measuring brain activity has given rise to a relatively new field of neuroscience research in recent decades. This chapter presents a brief overview of the biophysical bases of PET and fMRI, followed by a survey of experimental and analysis protocols. The analysis procedures discussed focus largely on fMRI rather than PET, since the former give rise to longer time series data sets to which the methods described in this book may be applied.

Keywords:   PET, fMRI, brain activity, neural dynamics, noise, data analysis
