Neurophilosophy and Alzheimer's Disease


Book Description

Any mention of the relationship, still poorly understood, between body (or brain) and mind invariably invokes the name of Descartes, who is often thought of as the father of modern philosophy and perhaps of neurophilosophy. Although a native of the heart of France (the region around Tours), Rene Descartes travelled widely, as everyone knows, especially to Holland and Sweden. It should come as no surprise, that the Congress of Neurophilosophy and Alzheimer's Disease was the first in the series of Fondation Ipsen Colloques Medecine et Recherche to be held outside France. The meeting was held in San Diego (California) on January 11, 1991. This venue was chosen for a number of reasons. The University of California San Diego is without doubt one of the most dynamic universities today. A good number of friends of the Fondation Ipsen who have taken part as speakers in previous conferences are based there. Patricia Churchland, whose publications have helped "launch" the term "neurophilosophy", also teaches there. The choice of this particular venue gave us the welcome opportunity of benefiting directly during the conference from the participation of many eminent (including some Nobel Prize-winning) scientists, including biochemists, neuro scientists and "alzheimerologist", psychologists, cognitive science specialists and philosophers.







Growth Factors and Alzheimer’s Disease


Book Description

The study of the relationships between neurotrophic factors (NGF, FGF, amyloid) and neurodegenerative disorders (especially Alzheimer's disease) is of major importance not only for understanding the pathogenesis of the latter, but also for the pharmacological approach to this disease. Information on the subject stemming from the symposium in Strasbourg in April, 1990, organized by the Fondation IPSEN is presented in this book. It provides stimulating hypotheses about the possible role of growth factors in the generation of senile plaques, the process of degeneration and regeneration in Alzheimer's disease, the expression of the gene of NGF and the possible use of NGF in treatment.




Synaptic Plasticity and the Mechanism of Alzheimer's Disease


Book Description

A biochemical hypothesis - that Alzheimer’s disease (AD) is a progressive cerebral amyloidosis caused by the aggregation of the amyloid b-protein (Ab) - preceded and enabled the discovery of etiologies. This volume serves as a record focused on bringing together investigators at the forefront of elucidating the structure and function of hippocampal synapses with investigators focused on understanding how early assemblies of Ab may compromise some of these synapses.




Mediating Alzheimer's


Book Description

An exploration of the representational culture of Alzheimer’s disease and how media technologies shape our ideas of cognition and aging With no known cause or cure despite a century of research, Alzheimer’s disease is a true medical mystery. In Mediating Alzheimer’s, Scott Selberg examines the nature of this enduring national health crisis by looking at the disease’s relationship to media and representation. He shows how collective investments in different kinds of media have historically shaped how we understand, treat, and live with this disease. Selberg demonstrates how the cognitive abilities that Alzheimer’s threatens—memory, for example—are integrated into the operations of representational technologies, from Polaroid photographs to Post-its to digital artificial intelligence. Focusing on a wide variety of media technologies, such as neuroimaging, art therapy, virtual reality, and social media, he shows how these cognitively oriented media ultimately help define personhood for people with Alzheimer’s. Media have changed the practices of successful aging in the United States, and Selberg takes us deep into how technologies like digital brain-training and online care networks shape ideas of cognition and healthy aging. Packed with startlingly fresh insights, Mediating Alzheimer’s contributes to debates around bioethics, the labor of caregiving, and a national economy increasingly invested in communication and digital media. Probing the very technologies that promise to save and understand our brains, it gives us new ways of understanding Alzheimer’s disease and aging in America.




Intracellular Traffic and Neurodegenerative Disorders


Book Description

Many adult onset neurodegenerative diseases arise from the accumulation of misfolded peptides. This book examines the role sub-cellular trafficking pathways play in the pathological accumulation of these misfolded proteins and in attempts to clear them.




Two Faces of Evil: Cancer and Neurodegeneration


Book Description

Homeostasis involves a delicate interplay between generative and degenerative processes to maintain a stable internal environment. In biological systems, equilibrium is established and controlled through a series of negative feedback mechanisms driven by a range of signal transduction processes. Failures in these complex communication pathways result in instability leading to disease. Cancer represents a state of imbalance caused by an excess of cell proliferation. In contrast, neurodegeneration is a consequence of excessive cell loss in the nervous system. Both of these disorders exhort profound tolls on humanity and they have been subject to a great deal of research designed to ameliorate this suffering. For the most part, the topics have been viewed as distinct and rarely do opportunities arise for transdisciplinary discussions among experts in both fields. However, cancer and neurodegeneration represent yin-yang counterpoints in the regulation of cell growth, and it is reasonable to hypothesize that key regulatory events mediated by oncogenes and tumor suppressor genes in cancer may also affect neurodegenerative processes




From Synapses to Rules


Book Description

One high-level ability of the human brain is to understand what it has learned. This seems to be the crucial advantage in comparison to the brain activity of other primates. At present we are technologically almost ready to artificially reproduce human brain tissue, but we still do not fully understand the information processing and the related biological mechanisms underlying this ability. Thus an electronic clone of the human brain is still far from being realizable. At the same time, around twenty years after the revival of the connectionist paradigm, we are not yet satisfied with the typical subsymbolic attitude of devices like neural networks: we can make them learn to solve even difficult problems, but without a clear explanation of why a solution works. Indeed, to widely use these devices in a reliable and non elementary way we need formal and understandable expressions of the learnt functions. of being tested, manipulated and composed with These must be susceptible other similar expressions to build more structured functions as a solution of complex problems via the usual deductive methods of the Artificial Intelligence. Many effort have been steered in this directions in the last years, constructing artificial hybrid systems where a cooperation between the sub symbolic processing of the neural networks merges in various modes with symbolic algorithms. In parallel, neurobiology research keeps on supplying more and more detailed explanations of the low-level phenomena responsible for mental processes.
