Advances in Brain Imaging Review of Psychiatry Series John M. Oldham, M.D. Michelle B. Riba, M.D., M.S. Series Editors No. 4 Washington, DC London, England Advances in Brain Imaging EDITED BY John M. Morihisa, M.D. Note: The authors have worked to ensure that all information in this book concerning drug dosages, schedules, and routes of administration is accurate as of the time of publication and consistent with standards set by the U.S. Food and Drug Administration and the general medical community. As medical research and practice advance, however, therapeutic standards may change. For this reason and because human and mechanical errors sometimes occur, we recommend that readers follow the advice of a physician who is directly involved in their care or the care of a member of their family. A product’s current package insert should be consulted for full prescribing and safety information.

Carter goes on to describe fascinating developments in cognitive xvi ADVANCES IN BRAIN IMAGING neuroscience that are important to the field of brain imaging Neuroimaging researchers have been able to build upon the basic work of cognitive neuroscience to assist in the interpretation of functional brain imaging findings Carter then emphasizes that when taken together, the work in these two fields of science... that abnormal brain images actually correlate with brain pathology In addition to emphasizing the therapeutic implications of brain- imaging findings, Callicott also suggests that this field may achieve its greatest utility in the search for the genetic bases of psychiatric disorders Indeed, Callicott’s most exciting theme is the future application of brain imaging in concert with genetic findings He gives... scientific advances When taken together, moreover, they begin to inspire one of the most valuable emotions that can be felt by researchers or clinicians in our field: hope for advancement in therapeutic interventions for our patients xviii ADVANCES IN BRAIN IMAGING Chapter 1 Functional Brain Imaging in Psychiatry The Next Wave Joseph H Callicott, M.D Early failure to identify brain lesions in psychiatric... psychiatric help xiv ADVANCES IN BRAIN IMAGING Foreword John M Morihisa, M.D In this new century the field of brain imaging will evolve and grow to fulfill the bright promise it has showed from its beginning over a generation ago This book includes the work of five scientists who are contributing to that growth by investigating a spectrum of psychopathologies using a variety of imaging approaches All have... Resonance Imaging (fMRI) in Psychiatry Advantages such as minimal invasiveness, no radioactivity, widespread availability, and virtually unlimited study repetitions make fMRI ideally suited to the study of in vivo brain function in psychiatry (Levin et al 1995) Before proceeding to the findings themselves, however, it is important to be mindful of the continued limitations of fMRI brain mapping (Weinberger... Nowhere in the field of medicine is technology advancing more rapidly than in brain imaging, generating a level of excitement that surely surpasses the historical moment when the discovery of the X ray first allowed us to noninvasively see into the living human body The new imaging methods, fortunately, do not involve the risk of radiation exposure, and the capacity of the newest imaging machines to... altering the way we conceptualize these illnesses In Chapter 4, Sackeim presents both structural and functional brain imaging findings in patients with late-life depression He reports that there is growing evidence suggesting that patients with this disorder demonstrate an excess of hyperintensities on Foreword xvii magnetic resonance imaging (MRI) Further, Sackeim discusses findings of decreased brain. .. approximately 21% increase in neuronal density (decrease in neuropil) The original intent of in vivo functional brain imaging was to illuminate the underlying physiological disturbances that lead to manifest illness Based on the neurological tradition, alterations in cerebral blood flow or metabolic rate were presumed to mark the brain lesions underlying loss of function However, no independent measures... like schizophrenia In addition, we will examine the use of proton magnetic resonance spectroscopic imaging ( 1H-MRSI) as a method for connecting functional findings with neuronal pathology Finally, in contrast to previous attempts to construe functional imaging findings as diagnostically relevant, we will discuss the use of such findings to guide the search for the genetic underpinnings of neuropsychiatric .
