WHOLE BRAIN EMULATION
INTRODUCTION:
The term emulation originates in computer science, where it denotes mimicking the function program or computer hardware by having its low‐level functions simulated by another program. While a simulation mimics the outward results, emulation mimics the internal causal dynamics. The emulation is regarded as successful if the emulated system produces the same outward behavior and results as the original.
Whole brain emulation (also referred to as mind uploading or mind transfer) is the hypothetical process of scanning and mapping a biological brain in detail and copying its state into a computer system or another computational device. The computer would have to run a simulation model so faithful to the original that it would behave in essentially the same way as the original brain, or for all practical purposes, indistinguishably. The simulated mind is assumed to be part of a virtual reality simulated world, supported by a simplified body simulation model.
In analogy to a software emulator, a brain emulator is software (and possibly dedicated non‐brain hardware) that models the states and functional dynamics of a brain at a relatively fine‐grained level of detail.
BRIEF HISTORY:
The first attempt at a careful analysis of brain emulation was a technical report (Merkle, 1989b) predicting, “a complete analysis of the cellular connectivity of a structure as large as the human brain is only a few decades away”. The report reviewed automated analysis and reconstruction methods, going into great detail on the requirements needed for parallel processing of brain samples using electron microscopes and image analysis software.
The first popularization of a technical description of a possible mind emulation scenario was found in Hans Moravec’s Mind Children (1998)
(Hanson, 1994) was the first look at the economical impact of copyable minds, showing that social role‐fit brain emulation would likely dramatic economic and demographic changes.
One sketch of a person emulation scenario (Leitl, 1995) was started out by the cryonic suspension of the brain, which was then divided into cubic blocks < 1mm. The blocks could individually be thawed for immune-staining or other contrast enhancement.
NEED FOR WHOLE BRAIN EMULATION:
1) There is a need to increase our understanding of complex neurocognitive processes such as memory, perception, learning, and decision-making. The mapping of the brain at the neuron level will ultimately allow us to create full simulations of brain functions.
2) Whole brain emulation would help in improving what we know about normal and abnormal human brain behavior.
3) Currently, there are limitations to model psychiatric illnesses and test models of the development, courses, and outcomes associated with these illnesses. WBE would help in overcoming this limitation.
4) WBE would enable understand traumatic brain injury in a better way. It would be possible to implant simulated brains into virtual bodies and simulate environmental changes. These simulations could be time-accelerated in a laboratory, which would provide insight into the risk and the protective factors and processes associated with mental health or organic brain conditions such as traumatic brain injury.
6. WBE has the potential to improve the human condition. * Speed-up: A computer-based intelligence such as an upload could potentially think much faster than a human even if it was no more intelligent. Eliezer Yudkowsky (Singularity Institute for Artificial Intelligence) proposed that a simulated brain could run about 1 million times faster than a real brain, experiencing about a year of subjective time in only 31 seconds of real time. * Immortality/Back-up: In theory, if the information and processes of the mind can be disassociated from the biological body, they are no longer tied to the individual limits and lifespan of that body. Furthermore, information within a brain could be partly or wholly copied or transferred to one or more other substrates (including digital storage or another brain), thereby reducing or eliminating mortality risk. This general proposal appears to have been first made in the biomedical literature in 1971 by renowned University of Washington bio-gerontologist George M. Martin. TECHNICAL REQUIREMENTS/CHALLENGES FOR WBE:
WBE is divided in three main steps: Scanning, Translation, Simulation.
Technological requirements/challenges for all the three are different and independent of each other.
a) Scanning: To be able to emulate the brain correctly, we need to first scan the structure of the brain correctly and accurately with highest possible resolution. Secondly, we need to make a device that can interface with the brain and read the data, state, identity, and etc. parameters of the brain without disturbing the original brain.
b) Translation: After we have captured the data from the brain, another challenge would be of storing the data in a form that can be searched and retrieved when required. We need to have the storage capabilities for storing such a huge amount of data and efficient programs to be able to analyze and understand the data.
c) Simulation: After having formed the complete structural analysis of the brain, one more challenge would be to artificially create a duplicate model, which acts in the same manner. We know that there are around 85 billion neurons in the brain and all are networked together. We need to create hardware equivalent to the functionality of 85 billion neurons, with a high internal bandwidth and reasonable size. When dealing with the problem of computational capacity, we need to look at two specific technologic laws; The Law of Accelerating Returns and Moore's Law. Fundamental limitation in this is the Moore’s Law, which sets a time limitation to reach such a giant structure.
SOFTWARE REQUIREMENTS FOR WHOLE BRAIN EMULATION:
Software able to handle such a big hardware and function similar to brain addressing the issues of identity, consciousness, computation power and intelligence would be required.
a) Approaches for scanning:
There are two approaches to meet the software requirement for Scanning Phase.
1) The first approach is to slice the brain to smallest possible size and then study the internal structure. And after that device a means to preserve and handle it(brain) properly during the entire scanning process. This is being done by two methods : * ALTUM - The Automatic Tape-Collecting Lathe Ultra microtome * KESM - The Knife-Edge Scanning Microscope
2) The other approach is to use the nano technology. This involves making very small nano devices that can go in the finer details of the brain and can be detected by some scanning mechanism to reveal the data.
b) Simulation: This would involve using a microprocessor for the function of each neuron and using optical communication means to have the maximum possible bandwidth. As the computational power of microprocessor is huge, a single microprocessor can handle the function of many neurons. No supercomputer available in the present time has either sufficient computational power or bandwidth to be able to simulate the brain. Presently, the super computers are being tested to perform a single function of the brain like speech processing, sight, etc.
BENEFITS OF BRAIN EMULATION:
1. As per Randal Keone (European neuro engineer and proprietor of MindUploading.org.), the anti-aging technologies don't aid in overcoming intellectual limitations. WBE would eliminate dependence on a single "substrate" and also take care of the intellectual limitations.
2. Whole brain emulation will allow neuroscientists to test out treatments for all sorts of neurological disorders, without actually risking real humans.
3. There are cases when people/patients face information-theoretic death i.e. they lose their memory. Whole brain emulation would be of great help in this case. (WBE would make it possible to copy the information in the mind). Whole brain emulation could be started, paused, backed-up and rerun from a saved backup state at any time.
4. Whole brain emulation may also greatly accelerate the development of artificial intelligence (AI) and perhaps move the field closer to its goal of artificial human general intelligence. This may also allow researchers to learn more about the “mind” of artificial intelligence and even the nature of consciousness itself.
5. WBE would increase the possibilities for simulating and testing real-world parallels.
6. WBE would allow for complex tests of diathesis – stress models of psychopathology. For example, researchers could model a brain with genetic or other pre-dispositional factors associated with depression and then apply simulated environmental stressors that may trigger the onset of the condition.
ISSUES:
There are various ethical, legal, religious and philosophical issues related to whole brain emulation:
Ethical Issues:
The ethical issues would involve challenges to the ideas of body identity, human immortality, property rights, capitalism, human intelligence, an afterlife, and man as created in God’s image. Often, these challenges cannot be distinguished from those raised by all technologies that extend human technological control over human bodies, e.g. organ transplant.
Legal Issues:
The only limited resources in a simulated world are computational resources, meaning simulation speed, and intellectual properties. It may be difficult for authorities to supervise that human rights are not threatened in any computer in the world. It might for example be tempting for social science researchers
to expose simulated minds, or whole isolated societies of simulated minds, to controlled experiments, where many copies of the same minds, or repeated reruns of the same simulation, are exposed to different test conditions.
Religious Issues:
The question whether an emulated brain can be a human mind is debated by philosophers and contradicted by the dualistic view of the human mind in many religions.
Philosophical Issues:
A philosophical issue with WBE is whether an emulated mind is really
 the “same” sentience, or simply an exact copy with the same memories and personality; or, indeed, what the difference could be between such a copy and the original.
Most projected brain scanning technologies, such as serial sectioning of the brain, would necessarily be destructive, and the original brain would not survive the brain scanning procedure. But if it can be kept intact, the computer-based consciousness could be a copy of the still-living biological person. It is in that case implicit that copying a consciousness could be as feasible as literally moving it into one or several copies, since these technologies generally involve simulation of a human brain in a computer of some sort, and digital files such as computer programs can be copied precisely. The problem is the possibility of creating a potentially infinite number of initially identical copies of the original person, which would of course all exist simultaneously as distinct beings.
CURRENT RELATED RESEARCHES:
There are a number of related initiatives that are underway. The major ones are:
1) The Blue Brain Project (Switzerland)
2) The proposed Brain Research through Advancing Innovative Neuro technologies (United States).
FUTURE RESEARCH: 1. New $1.6 billion supercomputer project will attempt to simulate the human brain.
An international group of researchers has secured $1.6 billion to fund the incredibly ambitious Human Brain Project. The researchers will be using a progressively scaled-up multilayered simulation running on a supercomputer.
And indeed, the project organizers are not thinking small. The entire team will consist of over 200 individual researchers in 80 different institutions across the globe. 2. 2045 Avatar Project:
2045 is a visionary project backed by Dmitry Itskov. The 2045 initiative held its first Global Future 2045 Congress in Moscow, in February 2012. There, over 50 world-leading physicists, biologists, anthropologists, sociologists, psychologists, and philosophers met seeking to develop a strategy for further development of the humankind. The three major steps of 2045 Avatar Project are: * First, the creation of a human-like robot dubbed “Avatar A,” and a state-of-the-art brain-computer interface system to link the mind with it. * Next, it be created a life support system for the human brain, which connects to the “Avatar A,” turning into “Avatar B.” * The third step, named “Avatar C”, is developing an artificial brain in which to transfer one’s individual consciousness with the goal of achieving cybernetic immortality.
CONCLUSION:
WBE is a deeply challenging and long-term prospect. Given current neuro-scientific and technological knowledge there doesn't seem to exist any fundamental obstacles, merely a large amount of engineering and research. A problematic issue for the feasibility of WBE appears to be to bridge the high aims of structural validity with the limitation to just replicative validity.

Transhumanism In Paul Virilio's Crepuscular Dawn

...2000). This fundamentally means that a person’s mind is uploaded into a computational substrate, so the brain will not experience disease or decay. Nonetheless, other things need to be discussed before going deeper into that topic. It seems likely to transhumanists that there will be superintelligent machines that grace this planet. However, they do not just want to live near them as servants, they want to “keep up” with them (p. 2000). Consequentially, the transhumanists would always be augmenting their human intelligence so they can always “match the best artificial intelligence” (p. 2000). One way of keeping up with machine superintelligence is to simply “employ sophisticated AI technology as a tool” (p. 2000). As Shanahan states, this is essentially what humans had been doing thus far. However, transhumanists believe that using AI technology as a tool is not enough in order to keep up with it, they would rather merge with it. In other words, Sophisticated AI technology would be interfaced directly to their brains, and the AI technology and the mind would work as one “bio-machine hybrid species” of astonishingly never seen before intellectual...

Is Superintelligence Feasible

...compared to my first draft. In my first paper I tended to overuse the same pronouns when referring to the author. I also did not compare and contrast the authors as well as I should have and did not supply any possible solutions to the problems the authors wrote about. In this draft I tried to do a better job of inserting quotes without using sentences starting with “this quote…” or “this quote highlights”. Also I gave my view on how we should approach singularity as my solution to the problems and uncertainties discussed in this paper. As a whole I believe this paper is way better than my first. The biggest thing I took away from this assignment is how vital technology has and will be in mankind’s existence today and continued survival. Also my researching skills have improved after the continued practice I had throughout this assignment. Superintelligence A Superintelligence is “any intellect that vastly outperforms the best human brains in practically every field, including scientific creativity, general wisdom, and social skills”; however, this definition leaves open how the super intelligence is implemented – it could be in a digital computer, an ensemble of networked computers, cultured cortical tissue, or something else. The ethical issues surrounding the creation of these machines with general intellectual capabilities that far outstrip those of humans are very different and have far greater implications than current ethical dilemmas. Superintelligence would not be...

Non-Viable National Economies

...Grace Lee 105 Korea The Political Philosophy of Juche Grace Lee Introduction The political philosophy known as juche became the official autarkic state ideology of the Democratic People’s Republic of Korea (DPRK) in 1972.1 Although foreign scholars often describe juche as “self-reliance,” the true meaning of the term is much more nuanced. Kim Il Sung explained: Establishing juche means, in a nutshell, being the master of revolution and reconstruction in one’s own country. This means holding fast to an independent position, rejecting dependence on others, using one’s own brains, believing in one’s own strength, displaying the revolutionary spirit of self-reliance, and thus solving one’s own problems for oneself on one’s own responsibility under all circumstances. The DPRK claims that juche is Kim Il Sung’s creative application of Marxist-Leninist principles to the modern political realities in North Korea.2 Kim Il Sung and his son Kim Jong Il have successfully wielded the juche idea as a political shibboleth to evoke a fiercely nationalistic drive for North Korean independence and to justify policies of self-reliance and self-denial in the face of famine and economic stagnation in North Korea. Kim Il Sung envisioned three specific applications of juche philosophy: political and ideological independence, especially from the Soviet Union and China; economic self-reliance and self-sufficiency; and a viable national defense system.3 This paper begins with a discussion of the three...

Philosophy to Psychology: Nature Versus Nurture

...Running Head: Philosophy to Psychology Philosophy to Psychology: The Question of Nature Versus Nurture Bernard Stevens Lux Ferre University Senior Research April 26, 2011 Abstract What influences more, society on the individual or collective individuals on society? Is society, thereby the individual, constructed by a set of pre-existing material conditions, or a pre-existing social condition? The philosophical origins of the question of nature versus nurture, are steeped in the ancient Greek philosophers nomos-physis debate in which the question is man the product (his actions) of conventional law or natural law? If so, is it possible to be balance of both, as suggested by Plato’s construction of the kallopolis (ideal city) in The Republic. For centuries, in Western Philosophy, the debate of which has dominion over man, nature or nurture, has been key to the establishment of many disciplines in the arts and sciences such as sociology, philosophy, and biology. Research suggest in ancient Greek civilization, the debate was termed as the Nomos-Physis debate, in which Plato challenged and/or expounded upon Pre-Socratic philosophers beliefs as to which rules man. The core subject matter is not, as in Psychology, a debate of which determines the personality traits of an individual per se, but whether or not man acts according to the laws of nature (Physis) or laws of man (Nomos).

...ADVERTISING'S FIFTEEN JIB FOWLES* BASIC APPEALS Emotional Appeals THE NATURE OF EFFECTIVE advertisements was recognized full well by the late media philosopher Marshall McLuhan . In his Understanding Media, the first sentence of the section on advertising reads, "The continuous pressure is to create ads more and more in the image of audience motives and desires ." By giving form to people's deep-lying desires, and picturing states of being that individuals privately yearn for, advertisers have the best chance of arresting attention and affecting communication . And that is the immediate goal of advertising : to tug at our psychological shirt sleeves and slow us down long enough for a word or two about whatever is being sold . We glance at a picture of a solitary rancher at work, and "Marlboro" slips into our minds . Advertisers (I'm using the term as a shorthand for both the products' manufacturers, who bring the ambition and money to the process, and the advertising agencies, who supply the know-how) are ever more compelled to invoke consumers' drives and longings ; this is the "continuous pressure" McLuhan refers to . Over the past century, the American marketplace has grown increasingly congested as more and more products have entered into the frenzied competition after the public's dollars. The economies of other nations are quieter than ours since the volume of goods being hawked does not so greatly exceed demand . In some economies, consumer wares...

Apollo, on the other hand, owned the engineering workstation business. Founded by industry veterans in 1980, Apollo provided high-performance workstations to Computervision's key competitors. Could Computervision bet its future on Sun? The Workstation Market Workstations, like personal computers (PCs), were designed to provide users with dedicated computing power. Historically, many users had shared the computing power of a single minicomputer or mainframe computer through more or less "dumb" terminals. Workstations and PCs, on the other hand, gave individuals their own CPUs (Central Processing Units—the "brains of a computer,”) at their own desks. There were, however, two important differences between workstations and PCs. First, workstations were designed to provide more computing power (close to a minicomputer's) and a greater variety of functions than were PCs. Bitmapped screens and graphics displays, for example, were considered standard in a workstation, but not in a personal computer. Correspondingly, a workstation sold for about $20,000, compared to a $5,000 to $7,000 unit cost for a PC. Second, while a PC system was entirely self-contained, workstations were usually attached to a network in order to share devices like printers and file...

Consumer Behavior

...CONSUMER BEHAVIOR PART ONE CONSUMER BEHAVIOR INTRODUCTION As the twentieth century has come to a close and we have moved into the third millennium, we can see many developments and changes taking place around us with all the industries and firms within each industry trying to keep pace with the changes and diverse needs of the people. Though for decades together, marketers have regarded ‘customer’ as the king and evolved all activities to satisfy this concept is gaining more momentum and importance today. This can largely be attributed to the prevailing market situation. Not only competition has become intense but over an above with the market being flooded with many products. The challenge before the marketers is to understand the diversity of consumer behavior and offer goods and services accordingly. Today the company image is built and made known by its customers. Thus the success of the firm will be determined by how effective it has been in meeting the diverse consumer needs and wants by treating each customer as unique and offering products and services to suit his needs and creating a life time value and relationship with him. (Nair 2004; 3) Marketers have come to realize that their effectiveness in meeting consumer needs directly influences their profitability the better they understand the factors underlying consumer behavior, the better able they are to develop effective marketing strategies to meet consumer needs.

...THE FUTURE OF EMPLOYMENT: HOW SUSCEPTIBLE ARE JOBS TO COMPUTERISATION?∗ Carl Benedikt Frey† and Michael A. Osborne‡ September 17, 2013 . Abstract We examine how susceptible jobs are to computerisation. To assess this, we begin by implementing a novel methodology to estimate the probability of computerisation for 702 detailed occupations, using a Gaussian process classifier. Based on these estimates, we examine expected impacts of future computerisation on US labour market outcomes, with the primary objective of analysing the number of jobs at risk and the relationship between an occupation’s probability of computerisation, wages and educational attainment. According to our estimates, about 47 percent of total US employment is at risk. We further provide evidence that wages and educational attainment exhibit a strong negative relationship with an occupation’s probability of computerisation.

Were the Europeans Correct in Thinking That the Native Americans Were Civilized

...National Humanities Center Resource Toolbox Becoming American: The British Atlantic Colonies, 1690-1763 “You know, we are different Nations and have different Ways.” European Americans and Native Americans View Each Other, 1700-1775 In British America, there was no greater sense of Otherness than between Europeans and Native Americans. Both Indians and Africans represented the "other" to white colonists, but the Indians held one card denied to the enslaved Africans— autonomy. As sovereign entities, the Indian nations and the European colonies (and countries) often dealt as peers. In trade, war, land deals, and treaty negotiations, Indians held power and used it. As late as 1755, an English trader asserted that "the prosperity of our Colonies on the Continent will stand 1 or fall with our Interest and favour among them."
