The study of self-consciousness helps humans understand themselves
and restores their identities. But self-consciousness has been a
mystery since the beginning of history, and this mystery cannot be
resolved by conventional natural science. In Self-Consciousness,
author Masakazu Shoji takes the mystery out of self-consciousness
by proposing the idea that the human brain and body are a
biological machine. A former VLSI microprocessor designer and
semiconductor physicist, Shoji was guided by the ideas of ancient
sages to create a conceptual design of a human machine brain model.
He explains how it works, how it senses itself and the outside
world, and how the machine creates the sense of existence of the
subject SELF to itself, just as a living human brain does. A
follow-up to Shoji's previous book, Neuron Circuits, Electronic
Circuits, and Self-Consciousness, this new volume examines
self-consciousness from three unconventional viewpoints to present
a complex theory of the mind and how self-consciousness develops.
Richard D. Alexander is an accomplished entomologist who turned his
attention to solving some of the most perplexing problems
associated with the evolution of human social systems. Using
impeccable Darwinian logic and elaborating, extending and adding to
the classic theoretical contributions of pioneers of behavioral and
evolutionary ecology like George Williams, William Hamilton and
Robert Trivers, Alexander developed the most detailed and
comprehensive vision of human social evolution of his era. His
ideas and hypotheses have inspired countless biologists,
anthropologists, psychologists and other social scientists to
explore the evolution of human social behavior in ever greater
detail, and many of his seminal ideas have stood the test of time
and come to be pillars of our understanding of human social
evolution. This volume presents classic papers or chapters by Dr.
Alexander, each focused on an important theme from his work.
Introductions by Dr. Alexander's former students and colleagues
highlight the importance of his work to the field, describe more
recent work on the topic, and discuss current issues of contention
and interest.

devolved from pure consciousness to this earthly realm.
A successful Wall Street trader turned neuroscientist reveals how
risk taking and stress transform our body chemistry
Before he became a world-class scientist, John Coates ran a
derivatives trading desk in New York City. He used the expression
"the hour between dog and wolf" to refer to the moment of
Jekyll-and-Hyde transformation traders passed through when under
pressure. They became cocky and irrationally risk-seeking when on a
winning streak, tentative and risk-averse when cowering from
losses. In a series of groundbreaking experiments, Coates
identified a feedback loop between testosterone and success--one
that can cloud men's judgment in high-pressure decision-making.
Coates demonstrates how our bodies produce the fabled gut feelings
we so often rely on, how stress in the workplace can impair our
judgment and even damage our health, and how sports science can
help us toughen our bodies against the ravages of stress. Revealing
the biology behind bubbles and crashes, "The Hour Between Dog and
Wolf "sheds new and surprising light on issues that affect us all.
This book looks at how the human brain got the capacity for
language and how language then evolved. Its four parts are
concerned with different views on the emergence of language, with
what language is, how it evolved in the human brain, and finally
how this process led to the properties of language. Part I
considers the main approaches to the subject and how far language
evolved culturally or genetically. Part II argues that language is
a system of signs and considers how these elements first came
together in the brain. Part III examines the evidence for brain
mechanisms to allow the formation of signs. Part IV shows how the
book's explanation of language origins and evolution is not only
consistent with the complex properties of languages but provides
the basis for a theory of syntax that offers insights into the
learnability of language and to the nature of constructions that
have defied decades of linguistic analysis, including including
subject-verb inversion in questions, existential constructions, and
long-distance dependencies. Denis Bouchard's outstandingly original
account will interest linguists of all persuasions as well as
cognitive scientists and others interested in the evolution of
language.
Collectively, the chapters in this work will provide the reader
with novel insight into the inter-relationships of the function of
different organelles in the sequences of events that lead to
cellular dysfunction and degeneration in the aging human
population. The chapters are rich in information for cell and
molecular biologists pursuing studies of the different diseases
covered. In addition, the clinician will find value in
understanding mechanisms underlying age-related disease as such an
understanding will lead to novel therapeutic approaches for an
array of age-related diseases.
Molecular mechanisms in visual transduction is presently one of the
most intensely studied areas in the field of signal transduction
research in biological cells. Because the sense of vision plays a
primary role in animal biology, and thus has been subject to long
evolutionary development, the molecular and cellular mechanisms
underlying vision have a high degree of sensitivity and
versatility. The aims of visual transduction research are
first
to determine which molecules participate, and then to understand
how they act in concert to produce the exquisite electrical
responses of the photoreceptor cells.
Since the 1940s 1] we have known that rod vision begins with the
capture of a quantum of energy, a photon, by a visual pigment
molecule, rhodopsin. As the function of photon absorption is to
convert the visual pigment molecule into a G-protein activating
state, the structural details of the visual pigments must be
explained from the perspective of their role in activating their
specific G-proteins. Thus, Chapters 1-3 of this Handbook
extensively cover the physico-chemical molecular characteristics of
the vertebrate rhodopsins. Following photoconversion and G-protein
activation, the phototransduction cascade leads to modifications of
the population of closed and open ion channels in the photoreceptor
plasma membrane, and thereby to the electrical response. The nature
of the channels of vertebrate photoreceptors is examined in Chapter
4, and Chapter 5 integrates the present body of knowledge of the
activation steps in the cascade into a quantitative framework. Once
the phototransduction cascade is activated, it must be subsequently
silenced. The various molecular mechanisms participating in
inactivation are
treated in Chapters 1-4 and especially Chapter 5. Molecular biology
is now an indispensable tool in signal transduction studies.
Numerous vertebrate (Chapter 6) and invertebrate (Chapter 7) visual
pigments have been characterized and cloned. The genetics and
evolutionary aspects of this great subfamily of G-protein
activating receptors are intriguing as they present a natural probe
for the intimate relationship between structure and function of the
visual pigments. Understanding the spectral characteristics from
the molecular composition can be expected to
This volume of "Advances in Cell Aging and Gerontology" critically
reviews the rapidly advancing area of telomerase research with a
focus at the molecular and cellular levels. The clearly established
function of telomerase is to maintain chromosome ends during
successive rounds of cell division by adding a six base DNA repeat
on to the telomeric ends of chromosomes. As presented in the
chapters of this volume, the mechanisms that regulate telomerase
expression and activity are complex. Moreover, emerging data
suggest additional roles for telomerase in the regulation of cell
differentiation and survival.
It is expected that this quite comprehensive volume will provide a
valuable resource for graduate students and postdocs in the
telomerase field and for established investigators in other fields
who are beginning to study telomerase in their particular research
program. With an increasing number of proteins being brought into
the fold of telomerase research (e.g., DNA damage and repair
response proteins, heat-shock proteins, and proteins in various
signal transduction cascades) many new scientists are beginning to
study this enzyme from novel vantage points.
This book reconstructs what the earliest grammars might have been
and shows how they could have led to the languages of modern
humankind.
Like other biological phenomena, language cannot be fully
understood without reference to its evolution, whether proven or
hypothesized," wrote Talmy Givon in 2002. As the languages spoken
8,000 years ago were typologically much the same as they are today
and as no direct evidence exists for languages before then,
evolutionary linguists are at a disadvantage compared to their
counterparts in biology. Bernd Heine and Tania Kuteva seek to
overcome this obstacle by combining grammaticalization theory, one
of the main methods of historical linguistics, with work in animal
communication and human evolution. The questions they address
include: do the modern languages derive from one ancestral language
or from more than one? What was the structure of language like when
it first evolved? And how did the properties associated with modern
human languages arise, in particular syntax and the recursive use
of language structures? The authors proceed on the assumption that
if language evolution is the result of language change then the
reconstruction of the former can be explored by deploying the
processes involved in the latter. Their measured arguments and
crystal-clear exposition will appeal to all those interested in the
evolution of language, from advanced undergraduates to linguists,
cognitive scientists, human biologists, and archaeologists.
During the past several years there has been a shortage of flight
opportunities for biological and medical projects. And those that
were available usually had severe restrictions on instrumentation,
number of subjects, duration, time allotted for performing the
experiments, a possibility for repetition of experiments. It is our
hope and expectation that this will change once the international
Space Station is in full operation. The advantages of a permanent
space station, already demonstrated by the Russian Mir station, are
continuous availability of expert crew and a wide range of
equipment, possibility of long-term experiments where this is
waranted, increased numbers of subjects through larger laboratory
space, proper controls in the large 1-G centrifuge, easier
repeatability of experiments when needed.
The limited number of flight opportunities during recent years
probably explains why it has taken so long to acquire a sufficient
number of high quality contributions for this seventh volume of
Advances in Space Biology and Medicine. While initially the series
wassailed at annually appearing volumes, we are now down to a
biannual appearance. Hopefully, it will be possible to return to
annual volumes in the future when results from space station
experimentation at beginning to pour in.
The first three chapters of this volume deal with muscle. Fejtek
and Wassersug provide a survey of all studies on muscle of rodents
flown in space, and include an interesting demography of this
aspect of space research. Riley reviews our current knowledge of
the effects of long-term spaceflight and re-entry on skeletal
muscle, and considers the questions still to be answered before we
can be satisfied that long-term space missions, such as on the
space station, can be safely undertaken. Stein reviews our
understanding of the nutritional and hormonal aspects of muscle
loss in spaceflight, and concludes that the protein loss in space
could be deleterious to health during flight and after return.
Strollo summarizes our understanding of the major endocrine systems
on the ground, then considers what we know about their functioning
in space, concluding that there is much to be learned about the
changes taking place during spaceflight. The many problems of
providing life support (oxygen regeneration and food supply) during
extended stay on the Moon, on Mars, or in space by means of plant
cultivation are discussed by Salisbury. The challenges of utilizing
electrophoresis in microgravity for the separation of cells and
proteins are illustrated and explained by Bauer and colleagues.
Finally, the chapter on teaching of space life sciences by Schmitt
shows that this field of science has come of age, but also that its
multidisciplinary character poses interesting challenges to
teaching it.
Gray's Anatomy, published in the UK in 1858 under the original
title Anatomy: Descriptive and Surgical, is a detailed English
textbook on human anatomy, focused on teaching medical students
human anatomy for practical knowledge during surgery. This unique
first edition includes more than 300 pages of illustrations by H.V.
Carter, M.D. Each image is labeled with the corresponding bones,
muscles, nerves, and organs. In addition, the book is separated
into chapters based on the systems of the body for easy use. While
Gray's Anatomy may no longer be a suitable study guide for modern
physicians, it is considered a classic work on the subject and is a
great reference for those interested in the origins of the study of
human anatomy. HENRY GRAY (1827-1861) was a renowned British
anatomist who studied at St George's Hospital Medical School in
London. His focus was on the endocrine glands and spleen until he
approached fellow colleague Henry Vandyke Carter to help him write
a comprehensive and accessible anatomy textbook. The team worked
for more than a year studying unclaimed cadavers to help write the
text. It was published in England in 1858 and in America only one
year later. Gray published the first two editions before it was
acquired by Longman's in 1863, shortly after Gray's early death
from smallpox.
The leading scholars in the rapidly-growing field of language evolution give readable accounts of their theories on the origins of language and reflect on the most important current issues and debates. As well as providing a guide to their own published research in this area they highlight what they see as the most relevant research of others. The authors come from a wide range of disciplines involved in language evolution including linguistics, cognitive science, computational science, primatology, and archaeology.
An expert palaeoarchaeologist reveals how our understanding of the
evolution of our species has been transformed by momentous
discoveries and technological advancements. Who are we? How do
scientists define Homo sapiens, and how does our species differ
from the extinct hominins that came before us? This illuminating
book explores how the latest scientific advances, especially in
genetics, are revolutionizing our understanding of human evolution.
Paul Pettitt reveals the extraordinary story of how our ancestors
adapted to unforgiving and relentlessly changing climates, leading
to remarkable innovations in art, technology and society that we
are only now beginning to comprehend. Drawing on twenty-five years
of experience in the field, Paul Pettitt immerses readers in the
caves and rockshelters that provide evidence of our African
origins, dispersals to the far reaches of Eurasia, Australasia and
ultimately the Americas. Popular accounts of the evolution of Homo
sapiens emphasize biomolecular research, notably genetics, but this
book also draws from the wealth of information from specific
excavations and artefacts, including the author's own
investigations into the origins of art and how it evolved over its
first 25,000 years. He focuses in particular on behaviour, using
archaeological evidence to bring an intimate perspective on lives
as they were lived in the almost unimaginably distant past.
Living organisms exhibit specific responses when confronted with
sudden changes in their environmental conditions. The ability of
the cells to acclimate to their new environment is the integral
driving force for adaptive modification of the cells. Such
adaptation involves a number of cellular and biochemical alteration
including metabolic homeostasis and reprogramming of gene
expression. Changes in metabolic pathways are generally short-lived
and reversible, while the consequences of gene expression are a
long-term process and may lead to permanent alternation in the
pattern of adaptive responses.
The heart possesses remarkable ability to adapt itself against any
stressful situation by increasing resistance to the adverse
consequences. Stress composes the foundation of many degenerative
heart diseases including atherosclerosis, spasm, thrombosis,
cardiomyopathy, and congestive heart failure. Based on the concept
that excessive stress may play a crucial role in the pathogenesis
of ischemic heart disease, attempts were made to design methods for
preventing of myocardial injury. Creation of stress reactions by
repeated ischemia and reperfusion or subjecting the hearts to heat
or oxidative stress enables them to meet the future stress
challenge. Repeated stress exposures adapt the heart to withstand
more severe stress reactions probably by upregulating the cellular
defense and direct accumulation of intracellular mediators, which
presumably constitute the material basis of increased adaptation to
stress. Thus, the powerful cardioprotective effect of adaptation is
likely to originate at the cellular and molecular levels that
compose fundamental processes in the prophylaxis of such diseases.
Volume six of the Advances in Organ Biology series contains
state-of-the-art reviews on myocardial preservation and cellular
adaptation from the leading authorities in this subject.
