![]() The technique is bound to attract some criticism, but McIntyre and colleagues believe that it will one day be possible to back up our brains and retrieve our memories in years to come. The company has already received backing from Y Combinator - an organization that helps to accelerate start-up companies - and Nectome will present their controversial idea at the company’s Demo Day next week. Still, the company plans to take advantage of “ death with dignity” Acts that have been passed in some states across America, including California, Oregon, and Washington.Īccording to McIntyre, Nectome are in talks with lawyers who are well versed in such Acts, and they believe that they will achieve legal backing to perform the procedure. While the preservation technique has shown some feasibility, scientists are still not sure whether it is even possible to retrieve memories from the human brain after death, and Nectome have yet to come up with a strategy that may enable them to “upload” retrieved memories. For a $10,000 deposit, you can sign up to the possibility of having your brain and memories preserved.Īccording to Nectome, 25 people have already signed up, despite the procedure not being fully fleshed out. Who would do such a thing? Well, Nectome have already rolled out a waiting list for the procedure, primarily as a way to achieve funding. This means that for Nectome to move their idea forward, they need to find people willing to die to have their brains fully preserved, in the hope that their memories can one day be retrieved and transformed into a computer simulation. Ideally, the procedure needs to be performed as a person is nearing the end of their life. In order for the brain to be fully preserved through vitrifixation, it needs to be fresh. ![]() There is one problem, however: although 2.5 hours between death and brain preservation doesn’t seem like too long, the brain suffers a great deal of damage in that time. Talking to MIT Technology Review, McIntyre claims that the lady’s brain is “one of the best-preserved ever.” Earlier this year, McIntyre and colleagues used vitrifixation to preserve the brain of an elderly woman just 2.5 hours after she died. The technique has already reached human testing. If you think that this all sounds a bit far-fetched, you might be interested to know that Nectome have already managed to preserve an entire rabbit brain using vitrifixation. As concentrations of ethylene glycol increase, the brain is put into a vitreous, or glass-like, state. This way, it can be stored for hundreds of years, according to Nectome.Ī chemical called ethylene glycol is applied to the brains prior to freezing, to stop the formation of ice crystals. In order to enhance preservation further, the brain is stored at -122☌. Fixation involves using a chemical called glutaraldehyde to solidify synapses and prevent them from degrading. “Vitrifixation” comprises two processes: fixation and vitrification. Using a technique called aldehyde-stabilized cryopreservation - also referred to as vitrifixation - Nectome believe that they could preserve human synapses, along with the memories they have helped to form. ![]() In other words, synapses allow brain cells to communicate with each other, and these structures are important for memory formation. ![]() Synapses are structures that pass electrical or chemical signals between neurons. The company - co-founded by Massachusetts Institute of Technology (MIT) graduate Robert McIntyre - says that soon, we may be able to preserve the human connectome and even “upload” our memories to the cloud.Īccording to the Brain Preservation Foundation, the connectome is a map of the brain’s neural connections, or those between brain cells. Introducing Nectome, an organization whose “ultimate ambition is to keep your memories intact for the future.” Share on Pinterest A start-up company claims it may one day be possible to preserve human brains and retrieve memories. ![]()
