How does the brain orchestrate perceptions, thoughts, and actions from the activity of its neurons? Addressing these challenging issues requires methods with sufficiently high temporal and spatial resolution of neuronal activity in both local and global networks as well as theories to advance understanding how different levels of brain dynamics interact. This book brings together leading investigators who represent various aspects of brain dyn...

The misfolding and aggregation of specific proteins is an early and obligatory event in many of the age-related neurodegenerative diseases of humans, and appears to occur many years before the onset of clinical symptoms. The initial cause of this pathogenic cascade and the means whereby disease spreads through the nervous system, remain uncertain. A recent surge of research, first instigated by pathologic similarities between prion disease and...

The health of the proteome depends upon protein quality control to regulate the proper synthesis, folding., translocation, and clearance of proteins. The cell is challenged constantyl by environmental and physiological stress, aging, and the chronic expressions of disease associated misfolded proteins. Substantial evidence supports the hypothesis that the expression of damaged proteins initiates a cascade of molecular events that leads to Alzh...

The two greatest medical fears of the aging population are cancer and Alzheimer’s disease. Despite dramatic advances in understanding the molecular etiology of these disorders, therapeutic options for many patients with advanced disease have changed little and outcomes remain dismal. Paradoxically, recent findings suggest that some of the same molecules and biochemical processes underlying cancer may also participate in neurodegeneration. Ther...

Characterizing the computational architecture and neurobiological mechanisms underlying consciousness is a major unsolved problem in cognitive neuroscience. Yet, thanks to new advances in stimulation paradigms, brain imaging techniques, and neuronal theorizing, the issue now appears to be empirically addressable. In this book thirteen renowned neuroscientists and clinicians examined the most recent data in the field including the possibility t...

What lies at the heart of neuronal plasticity? Accumulating evidence points to epigenetics. This word originally indicated potentially heritable modifications in gene expression that do not involve changes in DNA sequence. Today this definition is much less strict, and epigenetic control is thought to include DNA methylation, histone modifications, histone variants, microRNA metabolic pathways and non-histone proteins modifications. Thus, whil...

Traditionally, neuroscience has considered the nervous system as an isolated entity and largely ignored influences of the social environments in which humans and many animal species live. In fact, we now recognize the considerable impact of social structures on the operations of the brain and body. These social factors operate on the individual through a continuous interplay of neural, neuroendocrine, metabolic and immune factors on brain and ...
