Brain Science – serie

This book presents a new view on the evolution of the brain, cognition, and emotion. Around a half-century ago, Professor Harry Jerison published a seminal book entitled Evolution of the Brain and Intelligence. Since then, there has been a series of dramatic methodological and conceptual changes which have led to many new insights into the understanding of brain evolution and cognition. This book is particularly focused on three significant aspects of such changes. First, taking advantage of a new integrated approach called evolutionary developmental biology or Evo/Devo, researchers have started to look into vertebrate brain evolution from the developmental perspective. Second, comparative neuroanatomists have accumulated a large amount of information about the brains of diverse animal groups to refute the old-fashioned idea that vertebrate brains evolved linearly from non-mammals to mammals. Third, comparative behavioral studies have demonstrated that sophisticated cognition and emotion are not unique to some primates but are also found in many non-primate and even non-mammalian species. This work will appeal to a wide readership in such fields as neuroscience, cognitive science, and behavioral science.

This book provides accurate, comprehensive, and convenient reference for usages of the “freely rotatable three dimensional combined Nissl-stained and MRI digital data of the marmoset brain”. The key features of the original 3D digital data and of this atlas are: 1. The original digital datasets are freely rotatable in three dimensions, thus expected to be useful for any disciplines and anatomical interest, using any coordinate system, 2. Combined Nissl stained and MRI images are obtained from the same marmoset, to allow cross-modality matched references for multiple usages, 3. 86 Horizontal Series of Images with Neurosurgical Plane (based on the actual data), with more accuracy and resolution (Chapter 2) than the web-based digital images, 4. 32 Coronal Series of Images with Neurosurgical Plane (reproduced from the brain model) (Chapter 3), 5. 10 Parasagittal Series of Images with Neurosurgical Plane (reproduced from the brain model) (Chapter 4), 6. 3 Omnidirectionally Sliceable Planes (reproduced from the brain model) (Chapter 5), 7. In order to provide higher resolution structures to match systematic accuracy for supplementation of the digital data on the website, additional information are included. They are: 1) Nomenclature, 2) List of Brain Structures in Hierarchical Order, 3) Index of Abbreviations, together with 143 useful Bibliographic References list as of 2016, 8. Horsley-Clarke’s stereotaxic coordinates were adopted in the present atlas.

This book is the first digital atlas of the degu brain with microscopic features simultaneously in Nissl sections and magnetic resonance imaging (MRI). As an experimental animal model, the degu contributes to a variety of medical research fields in diabetes, hyperglycemia, pancreatic function, and adaptation to high altitude, among others. Recently the degu has gained increasing importance in the field of neuroscience, particularly in studies evaluating the relationship between sociality and cognitive brain functions, and in studies pertaining to the evolutional aspects of the acquisition of tool-use abilities. Furthermore, aging-related brain dysfunction in humans can be studied using this animal model in addition to mammals with much longer lifespans. This brain atlas is constructed to provide histological and volume-rendered information simultaneously, fitting with any spatial coordination in brain positioning. It can be a useful guide to degus as well as to other rodents for studies of brain structures conducted using MRI or other contemporary examination methods with volume-rendering functions.

The prefrontal cortex is known to play important roles for performing a variety of higher cognitive functions. Among regions of the prefrontal cortex, the dorsolateral prefrontal cortex plays the most important roles for these functions. This book focuses on functions of the dorsolateral prefrontal cortex, summarizes research results obtained mainly by non-human primate studies, and describes neural mechanisms of executive functions that the dorsolateral prefrontal cortex participates. First, to understand the feature of the dorsolateral prefrontal cortex and how its function has been understood, anatomical and functional features of the dorsolateral prefrontal cortex and historical overview of prefrontal functions are described. To understand functions of the prefrontal cortex and neural mechanisms of executive functions, working memory is an important concept and sustained activation during the memory period of working memory tasks is known as a neural mechanism of working memory.Therefore, this book describes features of sustained memory-related activity based on neurophysiological results obtained in the prefrontal cortex and how memory-related activity contributes to executive functions including control of attention, inhibitory control, task management, and planning. And further, this book describes how the dorsolateral prefrontal cortex contributes to neural mechanisms for sensory and motor processing, memory control in multi-task performance, decision-making, metacognition, and top-down control. Thus, this book provides important information regarding neural mechanisms of dorsolateral prefrontal functions to neuroscientists and helps to plan further investigation to understand prefrontal functions in primates and human subjects.
