Prior to the publication of the first edition of this book in 2004, existing texts were targeted toward practicing scientists, and assumed a level of expertise not possessed by most students. Functional Magnetic Resonance Imaging was the first textbook to provide a true introduction to fMRI designed with undergraduate students, graduate students, and beginning researchers in mind. Changes in the Second Edition include: Revised MR physics chapters that include parallel conceptual and quantitative paths, allowing students from diverse backgrounds and interests to readily navigate these topics. Expanded discussion of fMRI data analysis, with separate chapters on standard hypothesis-driven analyses and advanced exploratory analyses. Expanded coverage of experimental design that includes new approaches to efficient creation of fMRI experiments. Revised discussion of the physiological basis of fMRI to include recent discoveries about the origins of the BOLD response. A new Ethics chapter that discusses controversies, ethical and social concerns, and popular interpretations of fMRI research. Increased coverage of the integration of fMRI with other cognitive neuroscience techniques. New topics in the Advanced Methods chapter, reflecting cutting-edge developments in the field. Updated references and suggested readings throughout.

For over thirteen years I have documented my attempts to track a technology that allows the US government to read our thoughts. FMRI is one name but they can hide files in all kinds of ways. I am very concern about a technology that allows any person or group to invade our last temple (our brain). Old Venice history stated that no one person or group of persons could hold absolute power. The power and decisions must fall to all the people. This is why I raise this issue. How could Bin-laden attach us. How have they been using this technology and how are they going to use this technology in the future. The people must get involved and start questioning our leaders on this issue. Do your own research and do something to protect our civil liberties, now.

Genre: Medical

During the last two decades, new developments in functional MRI (magnetic resonance imaging) have made it possible to detect changes in the brain over time, as opposed to the "snapshot" produced by conventional MRI. Essentials of Functional MRI breaks down the technical challenges for physicians, researchers, and technologists who use functional MRI but may not be experts in the necessary math and physics. The author describes the theory and practical details of functional MRI (fMRI) methodology, including how to acquire and analyze images, and a wide range of examples demonstrate how fMRI has been used thus far. The author provides the essential information to study, understand, use, and teach the practical aspects of fMRI for those people who are most likely to extend its use into clinical practice.

Neuropsychological and Functional Magnetic Resonance Imaging Investigations of Anterior Temporal Lobe Language Function in Patients with Epilepsy

ISBN: OCLC:318778078
Release Date: 2007
Genre: Epilepsy

The anterior temporal lobe (ATL) sustains a degree of damage during surgery for temporal lobe epilepsy (TLE), and although classical language models implicate the ATL in language function, and naming difficulties are commonly reported by TLE patients post-surgically, the role of the ATL in language is not well understood. The present study aimed to examine the role of the ATL in language function, and methods for evaluating pre- and post-surgical language function of the ATL in patients with epilepsy using two approaches. The first study employed neuropsychological testing of pre-and post-surgical TLE patients on 3 conventional tests of language function, the Boston Naming Test (BNT), Controlled Oral Word Association Test (COWAT) and Animal Fluency, and one novel test: The Category Specific Names Test (CSNT). The CSNT was selected in an attempt to compensate for the problems of heterogeneous items, and the low ceiling in the BNT. Results of the CSNT had not been previously validated with TLE patients, and had not been routinely used in Australia. The second study looked at ATL activation in healthy controls and TLE patients using two new functional magnetic resonance imaging (fMRI) tasks. For the neuropsychological study, Bayesian analysis showed that the BNT was effective in differentiating left from right TLE in a sample of 42 patients with intractable epilepsy (LR+ = 8.37). The COWAT, Animal Fluency and the CSNT were not effective in differentiating left from right TLE. Very small likelihood ratios indicated only modest changes from pre-test odds. For the fMRI component of the study, although the two new fMRI tasks (Famous Faces naming, and Sentence Reading) resulted in the expected activation of language areas in group averaged data, they did not elicit consistent ATL activation across individuals, and subsequently did not meet the iii criteria recommended for fMRI protocol development recommended by Schwartz, Devinsky, Doyle and Perrine. (1997). Their inclusion in an fMRI protocol was not supported. Findings of the present study have important implications for pre-surgical evaluation of ATL language function in patients with epilepsy. Preliminary evidence was not found to support the use of the CSNT in patients with epilepsy. Results suggest that the BNT alone should be used for detecting naming impairment in patients with left-sided epilepsy. Benefits of using Bayesian analysis to examine the clinical applicability of research results, rather than conventional Null Hypothesis Significance Testing (parameter statistical) techniques are discussed.
