This book offers an overview of the most widely used statistical methods of analyzing fMRI data. An fMRI experiment produces massive amounts of highly complex data; researchers face significant challenges in analyzing the data they collect. Statistics plays a crucial role in understanding the nature of the data and obtaining relevant results that can be used and interpreted by neuroscientists. Standard analysis of fMRI data relies on a general linear model (GLM) approach to separate stimulus induced signals from noise. Using a minimum of jargon, it explains the concepts behind processing of fMRI data, focusing on the techniques that are most commonly used in the field. It can noninvasively detect signal changes in areas of the brain where neuronal activity is varying. A block paradigm produces alternating sequences of images (e.g., rest versus motor task). The field that has grown around the acquisition and analysis of fMRI data is intrinsically interdisciplinary in nature and involves contributions from researchers in neuroscience, psychology, physics and statistics, among others.

In recent years there has been explosive growth in the number of neuroimaging studies performed using functional Magnetic Resonance Imaging (fMRI). Crucially, this approach relies on a number of assumptions about the data which, for inferences to be valid, must be met. These plots illustrate that, the wavelet analysis of image registration when studying the statistical properties of package (Dinov and Sumners, 2001). In recent years there has been explosive growth in the num- ber of neuroimaging s tudies performed using f unctional Magnetic. Our acquisition strategy is based on repeatedly measuring the low spatial frequencies present in the MR signal, allowing us to ob-tain a low spatial resolution snapshot of the brain with extremely high temporal resolution (100 ms compared to the standard 2000 ms). This book offers an overview of the most widely used statistical methods of analyzing fMRI data. Statistical Analysis of fMRI Data, 2e by Ashby, 9780262042680. One of the most intriguing questions facing modern science is the inner workings of the human brain. After completion of these steps, statistical single subject and group analyses can be performed. Statistical analysis essentially asks how likely it is to obtain a certain effect (e.g., difference of condition means) in a data sample if there is no effect at the population level, i.e., how likely it is that an observed sample effect is solely the result of noise fluctuations.
