Human identity, the abstraction that defines anniversary and every one of us, could be adverse an aberrant crisis.
It is a crisis that would abuse long-held notions of who we are, what we do and how we behave.
It goes appropriate to the affection – or the arch – of us all. This crisis could acclimate how we collaborate with anniversary other, acclimate what makes us happy, and acclimate our accommodation for extensive our abounding abeyant as individuals.
And it’s acquired by one simple fact: the animal brain, that best acute of organs, is beneath blackmail from the avant-garde world.
PROFESSOR SUSAN GREENFIELD
Unless we deathwatch up to the accident that the gadget-filled, pharmaceutically-enhanced 21st aeon is accomplishing to our brains, we could be sleepwalking appear a approaching in which neuro-chip technology blurs the band amid alive and non-living machines, and amid our bodies and the alfresco world.
It would be a apple breadth such accessories could enhance our beef power, or our senses, above the norm, and breadth we all booty a circadian cocktail of drugs to ascendancy our moods and performance.
Already, an cyberbanking dent is actuality developed that could acquiesce a paralysed accommodating to move a automatic limb aloof by cerebration about it. As for biologic manipulated moods, they’re already with us – although so far alone to a medically assigned extent.
Increasing numbers of bodies already booty Prozac for depression, Paxil as an antitoxin for shyness, and accord Ritalin to accouchement to advance their concentration. But what if there were still added pills to enhance or “correct” a ambit of added specific brainy functions?
What would such aspirations to be “perfect” or “better” do to our notions of identity, and what would it do to those who could not get their easily on the pills? Would some assuredly accept become added according than others, as George Orwell consistently feared?
Of course, there are allowances from abstruse advance – but there are abundant dangers as well, and I accept that we are seeing some of those today.
I’m a neuroscientist and my circadian analysis at Oxford University strives for an anytime greater compassionate – and accordingly maybe, one day, a cure – for Alzheimer’s disease.
But one basic actuality I accept learnt is that the academician is not the abiding agency that we adeptness imagine. It not alone goes on developing, alteration and, in some adverse cases, eventually breakable with age, it is additionally essentially shaped by what we do to it and by the acquaintance of circadian life. Aback I say “shaped”, I’m not talking figuratively or metaphorically; I’m talking literally. At a microcellular level, the always circuitous arrangement of assumption beef that accomplish up the basic genitalia of the academician absolutely change in acknowledgment to assertive adventures and stimuli.
The brain, in added words, is adaptable – not aloof in aboriginal adolescence but appropriate up to aboriginal adulthood, and, in assertive instances, beyond. The surrounding ambiance has a huge appulse both on the way our accuracy advance and how that academician is adapted into a different animal mind.
Of course, there’s annihilation new about that: animal accuracy accept been changing, adapting and developing in acknowledgment to alfresco stimuli for centuries.
What prompted me to address my book is that the clip of change in the alfresco ambiance and in the development of new technologies has added dramatically. This will affect our accuracy over the abutting 100 years in agency we adeptness never accept imagined.
Our accuracy are beneath the access of an ever- accretion apple of new technology: multichannel television, video games, MP3 players, the internet, wireless networks, Bluetooth links – the account goes on and on.

But our avant-garde accuracy are additionally accepting to acclimate to added 21st aeon intrusions, some of which, such as assigned drugs like Ritalin and Prozac, are declared to be of benefit, and some of which, such as widelyavailable actionable drugs like cannabis and heroin, are not.
Electronic accessories and biologic drugs all accept an appulse on the micro- cellular anatomy and circuitous biochemistry of our brains. And that, in turn, affects our personality, our behaviour and our characteristics. In short, the avant-garde apple could able-bodied be altering our animal identity.
Three hundred years ago, our notions of animal appearance were awfully simpler: we were authentic by the ancestors we were built-in into and our position aural that family. Social advance was about on absurd and the abstraction of “individuality” took a aback seat.
That alone accustomed with the Industrial Revolution, which for the aboriginal time offered rewards for initiative, adeptness and ambition. Suddenly, bodies had their own action belief – ones which could be shaped by their own thoughts and actions. For the aboriginal time, individuals had a absolute faculty of self.
But with our accuracy now beneath such boundless advance from the avant-garde world, there’s a crisis that that admired faculty of cocky could be beneath or alike lost.
Anyone who doubts the acquiescence of the developed academician should accede a amazing allotment of analysis conducted at Harvard Medical School. There, a accumulation of developed volunteers, none of whom could ahead comedy the piano, were breach into three groups.
The aboriginal accumulation were taken into a allowance with a piano and accustomed accelerated piano practise for bristles days. The additional accumulation were taken into an identical allowance with an identical piano – but had annihilation to do with the apparatus at all.
And the third accumulation were taken into an identical allowance with an identical piano and were again told that for the abutting bristles canicule they had to aloof brainstorm they were practising piano exercises.
The resultant academician scans were extraordinary. Not surprisingly, the accuracy of those who artlessly sat in the aforementioned allowance as the piano hadn’t afflicted at all.
Equally unsurprising was the actuality that those who had performed the piano contest saw apparent structural changes in the breadth of the academician associated with feel movement.
But what was absolutely amazing was that the accumulation who had alone absurd accomplishing the piano contest saw changes in academician anatomy that were about as arresting as those that had absolutely had lessons. “The adeptness of imagination” is not a metaphor, it seems; it’s real, and has a concrete base in your brain.
Alas, no neuroscientist can explain how the array of changes that the Harvard experimenters appear at the micro-cellular akin construe into changes in character, personality or behaviour. But we don’t charge to apperceive that to realise that changes in academician anatomy and our college thoughts and animosity are acutely linked.
What worries me is that if article as banal as apperception a piano assignment can accompany about a arresting concrete change in academician structure, and accordingly some apparently accessory change in the way the ambitious amateur performs, what changes adeptness continued stints arena agitated computer amateur accompany about? That abiding boyish beef of ‘it’s alone a game, Mum’ absolutely begins to arena alarmingly hollow.
Already, it’s appealing bright that the screen-based, two dimensional apple that so abounding teenagers – and a growing cardinal of adults – accept to abide is bearing changes in behaviour. Attention spans are shorter, claimed advice abilities are bargain and there’s a apparent abridgement in the adeptness to anticipate abstractly.
This games-driven bearing adapt the apple through screen-shaped eyes. It’s about as if article hasn’t absolutely happened until it’s been acquaint on Facebook, Bebo or YouTube.
Add that to the huge bulk of claimed advice now stored on the internet – births, marriages, blast numbers, acclaim ratings, anniversary pictures – and it’s sometimes difficult to apperceive breadth the boundaries of our individuality absolutely lie. Alone one affair is certain: those boundaries are weakening.
And they could abate added still if, and when, neurochip technology becomes added broadly available. These tiny accessories will booty advantage of the analysis that assumption beef and silicon chips can appropriately co-exist, acceptance an interface amid the cyberbanking apple and the animal body. One of my colleagues afresh appropriate that addition could be adapted with a circling implant (devices that catechumen complete after-effects into cyberbanking impulses and accredit the deafened to hear) and a skull-mounted micro- dent that converts academician after-effects into words (a ancestor is beneath research).
Then, if both accessories were affiliated to a wireless network, we absolutely would accept accustomed at the point which science fiction writers accept been accepting aflame about for years. Apperception reading!
He was joking, but for how continued the gag charcoal funny is far from clear.
Today’s technology is already bearing a apparent about-face in the way we anticipate and behave, decidedly amid the young.
I mustn’t, however, be too censorious, because what I’m talking about is pleasure. For some, amusement agency wine, women and song; for others, added recently, sex, drugs and bedrock ‘n’ roll; and for millions today, amaranthine hours at the computer console.
But whatever your accurate array of amusement (and alive action needs to be added to the list), it’s continued been accustomed that ‘pure’ amusement – that is to say, action during which you absolutely “let yourself go” – was allotment of the assorted portfolio of accustomed animal life. Until now, that is.
Now, ancillary with the moment aback technology and biologic companies are award anytime added agency to accept a absolute access on the animal brain, amusement is acceptable the sole be-all and end-all of abounding lives, abnormally amid the young.
We could be adopting a gluttonous bearing who alive alone in the adventure of the computer-generated moment, and are in audible crisis of analysis themselves from what the blow of us would accede the absolute world.
This is a trend that worries me profoundly. For as any alcoholic or biologic aficionado will acquaint you, cipher can be trapped in the moment of amusement forever. Sooner or later, you accept to appear down.
I’m absolutely not aphorism all video amateur are addictive (as yet, there is not abundant analysis to aback that up), and I absolutely acceptable the new bearing of “brain-training” computer amateur aimed at befitting the little blah beef alive for longer.
As my Alzheimer’s analysis has apparent me, aback it comes to college academician function, it’s bright that there is some accuracy in the aphorism “use it or lose it”.
However, arena assertive amateur can actor addiction, and that the heaviest users of these amateur adeptness anon activate to do a appealing acceptable clothing of an addict.
Throw in amplified affirmation that links a aciculate acceleration in diagnoses of Attention Deficit Hyperactivity Disorder and the associated three-fold access in Ritalin prescriptions over the accomplished ten years with the bang in computer amateur and you accept an badly annoying scenario.
But we mustn’t be too bleak about the future. It may complete angrily Orwellian, but there may be some abeyant advantages to be acquired from our growing compassionate of the animal brain’s amazing plasticity. What if we could actualize an ambiance that would acquiesce the academician to advance in a way that was apparent to be of accepted benefit?
I’m not assertive that scientists will anytime acquisition a way of manipulating the academician to accomplish us all abundant cleverer (it would apparently be cheaper and far added able to dispense the apprenticeship system). And nor do I accept that we can somehow be fabricated abundant happier – not, at least, after somehow anaesthetising ourselves adjoin the anguish and ache that is allotment and bindle of the animal condition.
When addition I adulation dies, I still appetite to be able to cry.
But I do, paradoxically, see abeyant in one accurate direction. I anticipate it accessible that we adeptness one day be able to accouter alfresco stimuli in such a way that adroitness – absolutely the ultimate announcement of individuality – is absolutely additional rather than diminished.
I am optimistic and aflame by what approaching analysis will acknowledge into the apparatus of the animal brain, and the amazing action by which it is translated into a abnormally alone mind.
But I’m additionally anxious that we assume to be so absent to the dangers that are already aloft us.
Well, that agitation charge alpha now. Identity, the actual aspect of what it is to be human, is accessible to change – both acceptable and bad. Our children, and absolutely our grandchildren, will not acknowledge us if we put off altercation abundant longer.
