As is the case in evaluation of any future technology, it is unlikely that we can reliably predict all effects. Nevertheless, the potential for harm must be considered. The most obvious and basic problems involve safety. Evaluation of the costs and benefits of these implants requires a consideration of the surgical and long term risks. One question, whether the difficulties with development of non-toxic materials will allow long term usage?

Brain Chips by naveen kumar Rupalilal. Post to: Related Presentations: Yet the design has touched off a vigorous debate over the best approach to speeding up the neural networks increasingly used in computing.
The idea that neural networks might be useful in processing information occurred to engineers in the s, before the invention of modern computers. Only recently, as computing has grown enormously in memory capacity and processing speed, have they proved to be powerful computing tools. In recent years, companies including Google, Microsoft and Apple have turned to pattern recognition driven by neural networks to vastly improve the quality of services like speech recognition and photo classification.
But Yann LeCun, director of artificial intelligence research at Facebook and a pioneering expert in neural networks, said he was skeptical that IBMs approach would ever outpace todays fastest commercial processors. The chip appears to be very limited in many ways, and the performance is not what it seems, Mr.
LeCun wrote in an email sent to journalists. In particular, he criticized as inadequate the testing of the chips ability to detect moving pedestrians and cars.
This particular task, he wrote, wont impress anyone in computer vision or machine learning. LeCun said that while special-purpose chips running neural networks might be useful for a range of applications, he remained skeptical about the design IBM has chosen. Several neuroscience researchers and computer scientists disputed his critique.
The TrueNorth chip is like the first transistor, said Terrence J. It will take many generations before it can compete, but when it does, it will be a scalable architecture that can be delivered to cellphones, something that Yanns G.
According to Gill Pratt, the program manager, the agency is pursuing twin goals in its effort to design ultralow-power biological processors. The first, Dr. Pratt said, is to automate some of the surveillance done by military drones. We have lots of data and not enough people to look at them, he said. The second is to create a new kind of laboratory instrument to allow neuroscientists to quickly test new theories about how brains function.
Because of an editing error, an earlier version of this article misstated the day on which the report of a new computer chip was published. It was Thursday, not Wednesday. An article on Friday about a new IBM computer chip that is said to mimic the way a human brain works omitted the last word in the name of a program known by the acronym Synapse, which funded IBMs research. Machines found in research labs or vast data centers can perform such tasks, but they are huge and energy-hungry, and they need specialized programming.
Google recently made headlines with software that can reliably recognize cats and human faces in video clips, but this achievement required no fewer than 16, powerful processors.
A new breed of computer chips that operate more like the brain may be about to narrow the gulf between artificial and natural computationbetween circuits that crunch through logical operations at blistering speed and a mechanism honed by evolution to process and act on sensory input from the real world.
Advances in neuroscience and chip technology have made it practical to build devices that, on a small scale at least, process data the way a mammalian brain does. These neuromorphic chips may be the missing piece of many promising but unfinished projects in artificial intelligence, such as cars that drive themselves reliably in all conditions, and smart phones that act as competent conversational assistants.
Modern computers are inherited from calculators, good for crunching numbers, says Dharmendra Modha, a senior researcher at IBM Research in Alma den, California. Brains evolved in the real world.
Bound into intricate networks by threadlike appendages, neurons influence one anothers electrical pulses via connections called synapses. When information flows through a brain, it processes data as a fusillade of spikes that spread through its neurons and synapses.
You recognize the words in this paragraph, for example, thanks to a particular pattern of electrical activity in your brain triggered by input from your eyes. Crucially, neural hardware is also flexible: new input can cause synapses to adjust so as to give some neurons more or less influence over others, a process that underpins learning.
In computing terms, its a massively parallel system that can reprogram itself. Mead finally built his first neuromorphic chips, as he christened his brain-inspired devices, in the mids, after collaborating with neuroscientists to study how neurons process data.
By operating ordinary transistors at unusually low voltages, he could arrange them into feedback networks that looked very different from collections of neurons but functioned in a similar way. He used that trick to emulate the data-processing circuits in the retina and cochlea, building chips that performed tricks like detecting the edges of objects and features in an audio signal. But the chips were difficult to work with, and the effort was limited by chip-making technology.
With neuromorphic computing still just a curiosity, Mead moved on to other projects. It was harder than I thought going in, he reflects. A flys brain doesnt look that complicated, but it does stuff that we to this day cant do.
Thats telling you something. IBM makes neuromorphic chips by using collections of 6, transistors to emulate the electrical spiking behavior of a neuron and then wiring those silicon neurons together. Modhas strategy for combining them to build a brainlike system is inspired by studies on the cortex of the brain, the wrinkly outer layer. Although different parts of the cortex have different functions, such as controlling language or movement, they are all made up of so-called microcolumns, repeating clumps of to neurons.
Modha unveiled his version of a micro column in A speck of silicon little bigger than a pinhead, it contained silicon neurons and a block of memory that defines the properties of up to , synaptic connections between them. Programming those synapses correctly can create a network that processes and reacts to information much as the neurons of a real brain do.
Setting that chip to work on a problem involves programming a simulation of the chip on a conventional computer and then transferring the configuration to the real chip. In one experiment, the chip could recognize handwritten digits from 0 to 9, even predicting which number someone was starting to trace with a digital stylus.
In another, the chips network was programmed to play a version of the video game Pong. However, it is conceivable that there should be a higher standard for safety when technologies are used for enhancement rather than therapy, and this issue needs public debate.
Whether the informed consent of recipients should be sufficient reason for permitting implementation is questionable in view of the potential societal impact. Provisions should be made to facilitate upgrades since users presumably would not want multiple operations, or to be possessors of obsolete systems.
Manufacturers must understand and devise programs for teaching users how to implement the new systems. There will be a need to generate data on individual implant recipient usefulness, and whether all users benefit equally.
Additional practical problems with ethical ramifications include whether there will be a competitive market in such systems and if there will be any industry-wide standards for design of the technology. One of the least controversial uses of this enhancement technology will be its implementation as therapy.
It is possible that the technology could be used to enable those who are naturally less cognitively endowed to achieve on a more equitable basis. Certainly, uses of the technology to remediate retardation or to replace lost memory faculties in cases of progressive neurological disease, could become a covered item in health care plans.
Enabling humans to maintain species typical functioning would probably be viewed as a desirable, even required, intervention, although this may become a constantly changing standard.
The costs of implementing this technology needs to be weighed against the costs of impairment, although it may be that decisions should be made on the basis of rights rather than usefulness.
Consideration also needs to be given to the psychological impact of enhancing human nature. Will the use of computer-brain interfaces change our conception of man and our sense of identity?
If people are actually connected via their brains the boundaries between self and community will be considerably diminished. The pressures to act as a part of the whole rather than as a single isolated individual would be increased; the amount and diversity of information might overwhelm, and the sense of self as a unique and isolated individual would be changed.
Since usage may also engender a human being with augmented sensory capacities, the implications, even if positive, need consideration. Supersensory sight will see radar, infrared and ultraviolet images, augmented hearing will detect softer and higher and lower pitched sounds, enhanced smell will intensify our ability to discern scents, and an amplified sense of touch will enable discernment of environmental stimuli like changes in barometric pressure.
These capacities would change the "normal" for humans, and would be of exceptional application in situations of danger, especially in battle. As the numbers of enhanced humans increase, today's normal range might be seen as subnormal, leading to the medicalization of another area of life.
Thus, substantial questions revolve around whether there should be any limits placed upon modifications of essential aspects of the human species. Although defining human nature is notoriously difficult, man's rational powers have traditionally been viewed as his claim to superiority and the center of personal identity. Changing human thoughts and feeling might render the continued existence of the person problematical.
If one accepts, as most cognitive scientists do, "the materialist assertion that mind is an emergent phenomenon from complex matter, Modifying the brain and its powers could change our psychic states, altering both the self-concept of the user, and our understanding of what it means to be human.
The boundaries of the real and virtual worlds may blur, and a consciousness wired to the collective and to the accumulated knowledge of mankind would surely impact the individual's sense of self. Whether this would lead to bestowing greater weight to collective responsibilities and whether this would be beneficial are unknown.
Changes in human nature would become more pervasive if the altered consciousness were that of children. In an intensely competitive society, knowledge is often power. Parents are driven to provide the very best for their children. Will they be able to secure implants for their children, and if so, how will that change the already unequal lottery of life? The inequalities produced might create a demand for universal coverage of these devices in health care plans, further increasing costs to society.
However, in a culture such as ours, with different levels of care available on the basis of ability to pay, it is plausible to suppose that implanted brain chips will be available only to those who can afford a substantial investment, and that this will further widen the gap between the haves and the have-not.
A major anxiety should be the social impact of implementing a technology that widens the divisions not only between individuals, and genders, but also, between rich and poor nations.
As enhancements become more widespread, enhancement becomes the norm, and there is increasing social pressure to avail oneself of the "benefit. Beyond these more imminent prospects is the possibility that in thirty years, "it will be possible to capture data presenting all of a human being's sensory experiences on a single tiny chip implanted in the brain.
