Adaptation And The Brain

What role has natural selection played in shaping the structure and function of the vertebrate brain? This accessible book unravels the myriad adaptive explanations that have built up over decades, providing both a review and a critique of the work that has sought to explain which natural selection pressures have led to changes in brain size.

The author examines ideas of the nature and localization of the functions of the brain in the light of the philosophical constraints at work in the sciences of mind and brain in the 19th century. Particular attention is paid to phrenology, sensory-motor physiology and associationist psychology.

Finalist in the 2020 PROSE Awards This multidisciplinary volume examines the neural mechanisms underlying changes in the aging brain, changes in learning and memory, risk and protective factors, and the assessment and prevention of cognitive decline.

Living organisms have to constantly change their body to adjust its behaviors and functions to adapt to the constantly changing environment. This continuous interaction between the organism and the environment is called adaptation. The brain is the command center of the nervous system. It receives information from the environment through the sensory organs and sends signals to the muscles and other parts of the body. Emotional and behavioral adaptations require the involvement of the entire brain. The feature of the brain which helps humans learn and adapt to their surroundings and situations is called plasticity. This book unravels the recent studies in adaptation and brain function. The topics covered herein are of utmost significance and bound to provide incredible insights to readers. Through this book, we attempt to further enlighten the readers about the new concepts in this field.

"This book brings together a collection of studies from international researchers who demonstrate the brain's remarkable capacity to adapt its representation of the visual world in response to changes in its environment."--BOOK JACKET.

Theories of brain evolution stress communication and sociality are essential to our capacity to represent objects as intersubjectively accessible. How did we grow as a species to be able to recognize objects as common, as that which can also be seen in much the same way by others? Such constitution of intersubjectively accessible objects is bound up with our flexible and sophisticated capacities for social cognition understanding others and their desires, intentions, emotions, and moods which are crucial to the way human beings live. This book is about contemporary philosophical and neuroscientific perspectives on the relation of action, perception, and cognition as it is lived in embodied and socially embedded experience. This emphasis on embodiment and embeddedness is a change from traditional theories, which focused on isolated, representational, and conceptual cognition. In the new perspectives contained in our book, such 'pure' cognition is thought to be under-girded and interpenetrated by embodied and embedded processes.

Why does brain size vary so widely among vertebrate animal species? What role has natural selection played in shaping the structure and function of the vertebrate brain? This accessible book unravels the myriad adaptive explanations that have built up over decades, providing both a review and a critique of the work that has sought to explain which natural selection pressures have led to changes in brain size. Debate over the causes of variation in brain size, especially within extant humans and during the course of hominid evolution, has persisted for at least a couple of centuries. However, it was not until relatively recently that there has been sufficient data to allow a coherent (and taxonomically widespread) evolutionary perspective to emerge. The comparative approach employed by evolutionary biologists and behavioural ecologists has been particularly enlightening with regard to addressing variation in brain size. However, the extent to which correlational data - currently generated in some profusion - can provide a suitable explanation is not yet clear, and a constructively critical analysis of the relevant data is now timely. Five classes of selection pressure have formed the majority of explanations: ecology, technology, innovation, sex, and sociality. The book starts with a brief description of the difficulties of measuring both brain size and intelligence (cognition), before addressing the evidence for each of these five factors in turn. It argues that although ecology currently provides the most convincing explanation for variation in the size of brain regions, none of the factors yet offers a robust and compelling explanation for variation in whole brain size. The book concludes by looking forwards, suggesting the future steps necessary to reach such an explanation; steps that are challenging but now within reach. Adaptation and the Brain is suitable for graduate level students taking courses in animal behaviour and cognition, behavioural ecology, evolutionary ecology, psychology, and neuroscience as well as academics and professional researchers in these fields. The reader will not require a specific understanding of neuroscience, nor of the function of any particular brain region.
