Can you upload a human mind into a computer? A neuroscientist ponders what’s possible

by Dobromir Rahnev, Associate Professor of Psychology at Georgia Institute of Technology

The concept, cool yet maybe a little creepy, is known as mind uploading. Think of it as a way to create a copy of your brain, a transmission of your mind and consciousness into a computer. There you would live digitally, perhaps forever. You’d have an awareness of yourself, you’d retain your memories and still feel like you. But you wouldn’t have a body.

Within that simulated environment, you could do anything you do in real life – eating, driving a car, playing sports. You could also do things impossible in the real world, like walking through walls, flying like a bird or traveling to other planets. The only limit is what science can realistically simulate.

Doable? Theoretically, mind uploading should be possible. Still, you may wonder how it could happen. After all, researchers have barely begun to understand the brain.

Yet science has a track record of turning theoretical possibilities into reality. Just because a concept seems terribly, unimaginably difficult doesn’t mean it’s impossible. Consider that science took humankind to the Moon, sequenced the human genome and eradicated smallpox. Those things too were once considered unlikely.

As a brain scientist who studies perception, I fully expect mind uploading to one day be a reality. But as of today, we’re nowhere close.

Living in a laptop

The brain is often regarded as the most complex object in the known universe. Replicating all that complexity will be extraordinarily difficult.

One requirement: The uploaded brain needs the same inputs it always had. In other words, the external world must be available to it. Even cloistered inside a computer, you would still need a simulation of your senses, a reproduction of the ability to see, hear, smell, touch, feel – as well as move, blink, detect your heart rate, set your circadian rhythm and do thousands of other things.

But why is that? Couldn’t you just exist in a pure mental bubble, inside the computer without sensory input?

Depriving people of their senses, like putting them in total darkness, or in a room without sound, is known as sensory deprivation, and it’s regarded as a form of torture. People who have trouble sensing their bodily signals – thirst, hunger, pain, an itch – often have mental health challenges.

That’s why for mind uploading to work, the simulation of your senses and the digital environment you’re in must be exceptionally accurate. Even minor distortions could have serious mental consequences.

For now, researchers don’t have the computing power, much less the scientific knowledge, to perform such simulations.

Scanning billions of pinheads

The first task for a successful mind upload: Scanning, then mapping the complete 3D structure of the human brain. This requires the equivalent of an extraordinarily sophisticated MRI machine that could detail the brain in an advanced way. At the moment, scientists are only at the very early stages of brain mapping – which includes the entire brain of a fly and tiny portions of a mouse brain.

In a few decades, a complete map of the human brain may be possible. Yet even capturing the identities of all 86 billion neurons, all smaller than a pinhead, plus their trillions of connections, still isn’t enough. Uploading this information by itself into a computer won’t accomplish much. That’s because each neuron constantly adjusts its functioning, and that has to be modeled, too.

It’s hard to know how many levels down researchers must go to make the simulated brain work. Is it enough to stop at the molecular level? Right now, no one knows.

2045? 2145? Or later?

Knowing how the brain computes things might provide a shortcut. That would let researchers simulate only the essential parts of the brain, and not all biological idiosyncrasies. It’s easier to manufacture a new car knowing how a car works, compared to attempting to scan and replicate an existing car without any knowledge of its inner workings.

However, this approach requires that scientists figure out how the brain creates thoughts – how collections of thousands to millions of neurons come together to perform the computations that make the human mind come alive. It’s hard to express how very far we are from this.

Here’s another way: Replace the 86 billion real neurons with artificial ones, one at a time. That approach would make mind uploading much easier. Right now, though, scientists can’t replace even a single real neuron with an artificial one.

But keep in mind the pace of technology is accelerating exponentially. It’s reasonable to expect spectacular improvements in computing power and artificial intelligence in the coming decades.

One other thing is certain: Mind uploading will certainly have no problem finding funding. Many billionaires appear glad to part with lots of their money for a shot at living forever.

Although the challenges are enormous and the path forward uncertain, I believe that one day, mind uploading will be a reality. The most optimistic forecasts pinpoint the year 2045, only 20 years from now. Others say the end of this century.

But in my mind, both of these predictions are probably too optimistic. I would be shocked if mind uploading works in the next 100 years. But it might happen in 200 – which means the first person to live forever could be born in your lifetime.

"We would do best, I think, to remember that nothing in this universe is dependent upon our understanding of it for its existence. It's here whether we understand it or not and people frequently experience these things."

Comment on an article by Jeff Tarrant, Ph.D., BCN He was skeptical about psi abilities until he tested a woman who began spontaneously speaking South American tribal languages after participating in a holotropic breathwork session.

Tarrant writes, "I continued mapping brains and expanded my research to include telepathy, ESP, telekinesis, energy healing and mediumship. What started as a “random” story from a student turned into a decade of research which eventually formed the basis for the book ”Becoming Psychic: Lessons from the Minds of Mediums, Healers, and Psychics,” and convinced me that these abilities are real. Unlike what we see in the movies, they are not always consistent, and the results are not always mind-blowing."

Understanding the Brain: Insights from Dr. Schwarz's Book

April 13, 2025 Neurosurgeon Dr. Theodore Schwarz argues in his 2024 book, Grey Matters, that your brain defines you. He contends that “soul” and “mind” are English language constructs without scientific foundation. Millions of neurons, the brain’s nerve cells, transmit messages that store a person’s memories, knowledge, habits, and sensory details. These clusters of neurons form different lobes…

Penfield's homonculus: a fascinating map of our brain

What is Penfield's homonculus?

Penfield's homonculus is a simplified but highly illustrative graphic representation of how our brain ‘sees’ our body. It is a neurological map that shows how the different parts of our body are represented in the cerebral cortex. Imagine a deformed little man, with disproportionately large hands and mouth: that's the homunculus!

Two homunculi, two functions

There are two main types of homunculus:

- The motor homunculus: This corresponds to the area of the cerebral cortex that controls voluntary movements. In this homunculus, the parts of the body that we use with precision (hands, lips) occupy a much larger surface area than the parts that we use less (trunk, for example). This is because these areas require finer neuronal control.

- Sensory homunculus: This is the area of the cortex that receives sensory information from our body. As with the motor homonculus, the most sensitive areas (skin, lips) are disproportionately represented.

 Why is this representation so distorted?

The distortion of the homonculus does not reflect the actual size of the different parts of the body, but rather their functional importance in the brain. The more sensitive an area of the body or the more precise the motor control required, the larger the surface area it occupies on the homonculus.

How was the homonculus discovered?

It was the Canadian neurosurgeon Wilder Penfield who developed this mapping in the 1930s. While operating on epileptic patients, he electrically stimulated different areas of the cerebral cortex. He realised that stimulating certain areas triggered movements or sensations in specific parts of the body. By repeating these experiments, he was able to establish a correspondence between the different regions of the brain and the different parts of the body.

What are the implications of homonculus?

The discovery of the homonculus has had a major impact in several areas:

- Neurology: It has led to a better understanding of the mechanisms behind motor or sensory disorders, such as paralysis or loss of sensitivity.

- Neurosurgery: It helps neurosurgeons to plan their operations in such a way as to avoid damaging essential areas of the brain.

- Functional rehabilitation: It guides therapists in setting up rehabilitation programmes tailored to patients who have suffered brain damage.

Beyond the homonculus: brain plasticity

It is important to note that the homonculus is a static representation of the brain, but our brain is a dynamic and plastic organ. The connections between neurons can change throughout our lives as a result of learning and experience. For example, the homonculus of someone who plays the piano will be slightly different from that of someone who does not.

In conclusion

Penfield's homonculus is a valuable tool for understanding how our brain works. It reminds us that our brain is a complex, organised structure, in which each part has a precise function. Although this representation is simplified, it offers us a fascinating vision of how our body and mind are interconnected.
