When will I have the ability to add my mind to a laptop?


READER QUESTION: I’m 59 years previous, and in moderately good well being. Is it doable that I’ll stay lengthy sufficient to place my mind into a pc? — Richard Dixon.

We regularly think about that human consciousness is so simple as enter and output {of electrical} indicators inside a community of processing items – due to this fact similar to a pc. Actuality, nonetheless, is rather more difficult. For starters, we don’t truly know the way a lot info the human mind can maintain.

Two years in the past, a crew on the Allen Institute for Mind Science in Seattle, mapped the 3D construction of all of the neurons (mind cells) comprised in one cubic millimeter of the mind of a mouse – a milestone thought-about extraordinary.

This text is a part of Life’s Big Questions

The Dialog’s collection, co-published with BBC Future, seeks to reply our readers’ nagging questions on life, love, loss of life and the universe. We work with skilled researchers who’ve devoted their lives to uncovering new views on the questions that form our lives.


Inside this minuscule dice of mind tissue, the scale of a grain of sand, the researchers counted greater than 100,000 neurons and greater than a billion connections between them. They managed to document the corresponding info on computer systems, together with the form and configuration of every neuron and connection, which required two petabytes, or two million gigabytes of storage. And to do that, their automated microscopes needed to acquire 100 million pictures of 25,000 slices of the minuscule pattern constantly over a number of months.

Now if that is what it takes to retailer the total bodily info of neurons and their connections in a single cubic millimeter of mouse mind, you’ll be able to maybe think about that the gathering of this info from the human mind isn’t going to be a stroll within the park.

Knowledge extraction and storage, nonetheless, isn’t the one problem. For a pc to resemble the mind’s mode of operation, it could have to entry any and all of the saved info in a really quick period of time: the data would should be saved in its random access memory (RAM), quite than on conventional laborious disks. But when we tried to retailer the quantity of knowledge the researchers gathered in a pc’s RAM, it could occupy 12.5 instances the capability of the biggest single-memory computer (a pc that’s constructed round reminiscence, quite than processing) ever constructed.

The human mind comprises about 100 billion neurons (as many stars as may very well be counted within the Milky manner) – a million instances these contained in our cubic millimetre of mouse mind. And the estimated variety of connections is a staggering ten to the ability of 15. That’s ten adopted by 15 zeroes – a quantity similar to the person grains contained in a two meter thick layer of sand on a 1km-long seaside.

A query of house

If we don’t even know the way a lot info storage a human mind can maintain, you’ll be able to think about how laborious it could be to switch it into a pc. You’d must first translate the data right into a code that the pc can learn and use as soon as it’s saved. Any error in doing so would most likely show deadly.

A easy rule of knowledge storage is that you must ensure you have sufficient house to retailer all the data you must switch earlier than you begin. If not, you would need to know precisely the order of significance of the data you’re storing and the way it’s organised, which is way from being the case for mind information.

In the event you don’t know the way a lot info you must retailer while you begin, chances are you’ll run out of house earlier than the switch is full, which may imply that the data string could also be corrupt or unimaginable for a pc to make use of. Additionally, all information must be saved in at the least two (if not three) copies, to stop the disastrous consequences of potential information loss.

This is just one drawback. In the event you have been paying consideration after I described the extraordinary achievement of researchers who managed to completely retailer the 3D construction of the community of neurons in a tiny little bit of mouse mind, you’ll know that this was carried out from 25,000 (extraordinarily skinny) slices of tissue.
