Dr. Mark Bear is Picower Professor of Neuroscience in the Picower Institute for Learning and Memory, Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology.' Prior to moving to MIT in 2003, Dr. Bear was on the faculty of Brown University School of Medicine for 17 years where he held the Sidney and Dorothy Doctors Fox Chair in Visual Neuroscience.' He was an Investigator of the Howard Hughes Medical Institute for 22 years from 1994 to 2015, and served as Director of the Picower Institute from 2007 to 2009.'''''''''''' After receiving his B.S. degree from Duke University, Dr. Bear earned his Ph.D. degree in neurobiology at Brown.' He took postdoctoral training from Wolf Singer at the Max Planck Institute for Brain Research in Frankfurt, Germany, and from Leon Cooper at Brown.' Bear's laboratory has substantially advanced knowledge of how cerebral cortex is modified by experience.' He made fundamental discoveries on bidirectional synaptic plasticity, metaplasticity, the molecular basis of amblyopia (a cause of visual disability in children), and the pathophysiology of fragile X syndrome (the most common inherited cause of intellectual disability and autism).' He has been at the forefront of the efforts to translate knowledge of autism pathophysiology into new treatments. He has been recognized with a number of honors including the Brown University Class of 2000 Barrett Hazeltine Citation for Teaching Excellence, the Society for Neuroscience Young Investigator Award, the National Fragile X Foundation William & Enid Rosen Research Award, the Fragile X Research Foundation (FRAXA) Pioneer Award, the Ipsen Foundation Neural Plasticity Prize, the Beckman-Argyros Award in Vision Research, and election to the American Academy of Arts and Sciences.'

Neuroscience: Exploring the Brain, Fifth Edition takes a fresh, contemporary approach to the study of neuroscience, emphasizing the biological basis of behavior. The authors present material at the cutting edge of neuroscience in a way that is accessible to both science and nonscience students alike. The level of the material is comparable to an introductory college text in general biology.The human nervous system is examined at several different scales, ranging from the molecules that determine the functional properties of neurons to the large brain networks that underlie cognition and behavior. Many neuropsychiatric disorders are introduced as the book progresses, usually within the context of the specific neural system under discussion. Indeed, many insights into the normal functions of neural systems have come from the study of diseases that cause specific malfunctions of these systems. In addition, the authors discuss the actions of drugs and toxins on the brain using this information to illustrate how different brain systems contribute to behavior and how drugs may alter brain function.
