Inception becomes reality? Two teams of scientists implant ’false memories’ into mice


  • Teams can implant ‘synthetic memories’ into brains
  • Mice show fear as they ‘remember’ rooms where they had electric shocks
  • One team uses a drug, the other pulses of light

The idea of the surreal Hollywood
blockbuster Inception, where people  ‘plant’ an idea in someone else’s
head may not be so out-there after all.

Two teams of scientists have found ways to create false memories, and implant them into the brain at will – although for now, the technique only works in mice.

Memories are stored in a surprisingly small number of brain cells – and the teams could ‘control’ the cells to create ‘synthetic memories.’

The research raises the possibility that humans could be made to remember things that have not happened – or even ‘taught’ whole new skills using electronics or chemistry.

One technique used a drug to ‘turn on’ a memory of a different room in mice – making them remember a ‘safer’ room while in one where they had been given electric shocks.

‘We’ve essentially created a synthetic memory,’ says neuroscientist Mark Mayford of the Scripps Research Institute and the University of California, San Diego in La Jolla.

The other technique used pulses of light delivered to cells in a mouse’s brain.

‘The
expression of a specific memory, can be generated in a mammal by highly
specific physical activation of a specific small population of brain
cells,’ says Susumu Tonegawa,
Professor of Biology and Neuroscience at MIT.


Leonardo DiCaprio in Inception, a thriller based on the idea of 'planting' a fake memory in someone's head. Is the idea as far-fetched as it seems?

Tonegawa’s team used a light-activated
protein to ‘tag’ the tiny group of cells a memory appeared in as mice
were given electric shocks in a new environment.

The researchers found that they could trigger the same reaction again simply by applying light to the group of cells.

The brain cells ‘switched on’ and the mice immediately went into a defensive crouch.

To WH, Midlands, 24/3/2012 00:42 — You seem to have completely missed the point of my post. This was directed to those who, in the past, have insisted that life (and its corollary, thought) cannot come into existence except through the intervention of some external mystic entity. Work such as this demonstrates that life forms (and the mind) are but aggregates of simple components executing normal chemical reactions. I contend, therefore, that it is the complexity of the whole body which gives rise to self-awareness. As to your comment on living in Milton Keynes, this is the second time you have made this remark in recent weeks. It is childish and you really should understand that for those of us who live here, this is actually quite a pleasant location.

To DG, SB, 23/3/2012 23:46 — You say “We really must start rounding up the scientists and executing them now.” — I cannot see why you feel threatened by science or why you feel that a return to the ignorance of the Dark Ages would be beneficial. Presumably, by your reasoning, you would rather walk than use a car, not have clean food, public sanitation and water supplies and that you advocate treating illness with prayer and leeches, rather than with anti-biotics.

EB, Unless you live your life like a robot devoid of emotions and feelings it makes no sense in stating that life is “simply manifestations of electro-chemical reactions”. We’d all just be inanimate chunks of meat without them. Mind you, EB lives in Milton Keynes where implanting a false memory would actually be quite useful to numb the drudgery of existence.

But as we learn stuff, we pick up changes that have been made in the world. If we don’t pick up these changes, and have “knowledge” implanted into us, then we stop the evolution of knowledge. It would be like sticking to the same dictionary for hundreds of years. Suddenly, we’d all be out of date.

How do they know that some of the mice didn’t prefer the room with some of the non fatal electric shocks.After all all some humans don’t mind a bit of machismo.

We really must start rounding up the scientists and executing them now. If we do not, then we will have consigned ourselves to the dust bin. They will not stop until we do this.

The possibilities to help humans overcome trauma and PTSD would be amazing x

Sign me up! I’ll have the depressing memories erased and new, exciting memories planted.

In posts to this board over the past months, I have repeatedly stated that what we call “life” (and its corollary of “thoughts” and “emotions”) are simply manifestations of electro-chemical reactions. The experiments discussed in the report forming the subject of this article are a nice demonstration that this is correct. I trust that those who have disagreed with my posts will now reflect upon the information presented here.

I assumed everyone knew that? On that note i’m waiting until uploading the mind becomes possible, sounds fun!
