From Neurons To Self Consciousness

In the end, the author suggests that as more is learned about the working of the brain, philosophical problems that have caused centuries of speculation will simply be resolved by the facts of neurophysiology. --Book Jacket.

Many consider the nature of human consciousness to be one of the last great unsolved mysteries. Why should the light turn on, so to speak, in human beings at all? And how is the electrical storm of neurons under our skull connected with our consciousness? Is the self only our brain's user interface, a kind of stage on which a show is performed that we cannot freely direct? In this book, philosopher Markus Gabriel challenges an increasing trend in the sciences towards neurocentrism, a notion which rests on the assumption that the self is identical to the brain. Gabriel raises serious doubts as to whether we can know ourselves in this way. In a sharp critique of this approach, he presents a new defense of the free will and provides a timely introduction to philosophical thought about the self – all with verve, humor, and surprising insights. Gabriel criticizes the scientific image of the world and takes us on an eclectic journey of self-reflection by way of such concepts as self, consciousness, and freedom, with the aid of Kant, Schopenhauer, and Nagel but also Dr. Who, The Walking Dead, and Fargo.

This 2003 book focuses on neuropsychiatric models of self-consciousness, set against introductory essays describing the philosophical, historical and psychological approaches.

A unique and fascinating scientific detective story that traces the origins as well as the complex mechanisms of human self-consciousness.

This book discusses consciousness from the perspectives of neuroscience, neuropsychiatry and philosophy. It develops a novel approach in consciousness studies by charting the pathways in which the brain challenges the self and the self challenges the brain. The author argues that the central issue in brain studies is to explain the unity, continuity, and adherence of experience, whether it is sensory or mental awareness, phenomenal- or self-consciousness. To address such a unity is to understand mutual challenges that the brain and the self pose for each other. The fascinating discussions that this book presents are: How do the brain and self create the conspiracy of experience where the physicality of the brain is lost in the subjectivity of the self?

A summary of author Masakazu Shoji’s previous works, Self-Consciousness: Human Brain as Data Processor, explains self-consciousness by using a simple, mechanical model of the human brain, which reflects its past development of evolution by natural selection. The model was built from the information acquired from the unbiased, introspective observation of Shoji’s own mind and other rational assumptions. In this study, geared for those with a background in the research and science of psychology, Shoji introduces a new approach based on systems and information science; it relies on the synthetic method of study by designing the human brain’s functional model. It deals with the self-conscious directly, without adding in subconsciousness or quantum mystery, as has been done previously. The model was designed realistically using hardware built with genetic instructions, using neurons as the elements of digital and analog operations. Shoji shares that versions of this model reveal how humans acquire and store memories of images of the outside objects, sense the images internally, execute necessary actions directed by the images, feel an emotional state by facing life’s events, and develop intelligence by accumulated experiences. The model also explains mysterious mental experiences, such as seeing dreams, daydreams, phantoms, ghosts, and feeling premonitions.

A highly original theory of how the mind-brain works, based on the author's study of single neuronal cells. In I of the Vortex, Rodolfo Llinas, a founding father of modern brain science, presents an original view of the evolution and nature of mind. According to Llinas, the "mindness state" evolved to allow predictive interactions between mobile creatures and their environment. He illustrates the early evolution of mind through a primitive animal called the "sea squirt." The mobile larval form has a brainlike ganglion that receives sensory information about the surrounding environment. As an adult, the sea squirt attaches itself to a stationary object and then digests most of its own brain. This suggests that the nervous system evolved to allow active movement in animals. To move through the environment safely, a creature must anticipate the outcome of each movement on the basis of incoming sensory data. Thus the capacity to predict is most likely the ultimate brain function. One could even say that Self is the centralization of prediction. At the heart of Llinas's theory is the concept of oscillation. Many neurons possess electrical activity, manifested as oscillating variations in the minute voltages across the cell membrane. On the crests of these oscillations occur larger electrical events that are the basis for neuron-to-neuron communication. Like cicadas chirping in unison, a group of neurons oscillating in phase can resonate with a distant group of neurons. This simultaneity of neuronal activity is the neurobiological root of cognition. Although the internal state that we call the mind is guided by the senses, it is also generated by the oscillations within the brain. Thus, in a certain sense, one could say that reality is not all "out there," but is a kind of virtual reality.
