Demystifying consciousness: how subjective experience can be explained by natural brain and evolutionary processes.Consciousness is often considered a mystery. How can the seemingly immaterial experience of consciousness be explained by the material neurons of the brain? There seems to be an unbridgeable gap between understanding the brain as an objectively observed biological organ and accounting for the subjective experiences that come from the brain (and life processes). In this book, Todd Feinberg and Jon Mallatt attempt to demystify consciousness-to naturalize it, by explaining that the subjective, experiencing aspects of consciousness are created by natural brain processes that evolved in natural ways. Although subjective experience is unique in nature, they argue, it is not necessarily mysterious. We need not invoke the unknown or unknowable to explain its creation.Feinberg and Mallatt flesh out their theory of neurobiological naturalism (after John Searle's biological naturalism) that recognizes the many features that brains share with other living things, lists the neural features unique to conscious brains, and explains the subjective-objective barrier naturally. They investigate common neural features among the diverse groups of animals that have primary consciousness-the type of consciousness that experiences both sensations received from the world and affects such as emotions. They map the evolutionary development of consciousness and find an uninterrupted progression over time, without inserting any mysterious forces or exotic physics. Finally, bridging the previously unbridgeable, they show how subjective experience, although different from objective observation, can be naturally explained.

A new theory of Neurobiological Emergentism that explains how sentience emerges from the brain. Sentience is the feeling aspect of consciousness. In From Sensing to Sentience, Todd Feinberg develops a new theory called Neurobiological Emergentism (NBE) that integrates biological, neurobiological, evolutionary, and philosophical perspectives to explain how sentience naturally emerges from the brain. Emergent properties are broadly defined as features of a complex system that are not present in the parts of a system when they are considered in isolation, but may emerge as a system feature of those parts and their interactions. Tracing a journey of billions of years of evolution from life to the basic sensing capabilities of single-celled organisms up to the sentience of animals with advanced nervous systems, including all vertebrates (for instance, fish, reptiles, birds, and mammals), arthropods (insects and crabs), and cephalopods such as the octopus, Feinberg argues that sentience gradually but eventually emerged along diverse evolutionary lines with the evolution of sufficiently neurobiologically complex brains during the Cambrian period over 520 million years ago. Ultimately, Feinberg argues that viewing sentience as an emergent process can explain both its neurobiological basis as well its perplexing personal nature, thus solving the historical philosophical problem of the apparent "explanatory gap" between the brain and experience.

What can dementia, delusions, and other neurological disorders teach us about how the brain creates personal identity and a unified sense of self? Here, a leading neurobiologist offers an intriguing scientific approach to understanding the neurobiology of the self. Drawing on both the latest neuroscientific research, as well as the author's decades of experience with neurological patients, From Axons to Identity examines the link between brain and identity in fascinating new ways. Dr. Feinberg presents case studies of individuals with brain pathologies and unusual psychiatric syndromes that cause them to deny parts of their bodies or believe in the presence of mysterious imposters or imaginary friends, and then presents a groundbreaking new theory of these conditions that relates them to the normal course of psychological development. By examining what goes wrong in individuals with these conditions, Dr. Feinberg presents an engaging new theory with far-reaching implications for the link between brain and identity. From Axons to Identity proposes a new view of the processes of the brain and the self that is unique and revelatory.
