And every day, Reggie and his team put electrodes onto the skin on my lower back, pushed electricity into my spinal cord to excite my nervous system, as I walked in my exo.

Despite being paralyzed and not having any sensation from mid-chest to the tip of his toes as the result of a car crash six years ago that killed his brother and produced a complete spinal cord lesion that left Juliano in a wheelchair, Juliano rose to the occasion, and on this day did something that pretty much everybody that saw him in the six years deemed impossible.

But what the spinal cord lesion did not rob from Juliano was his ability to dream.

It's nothing but using sensors to read the electrical brainstorms that a brain is producing to generate the motor commands that have to be downloaded to the spinal cord, so we projected sensors that can read hundreds and now thousands of these brain cells simultaneously, and extract from these electrical signals the motor planning that the brain is generating to actually make us move into space.

If you have a complete lesion of the spinal cord, you cannot move because your brainstorms cannot reach your muscles.

But what Brazil wanted to do is to showcase a completely different country, a country that values science and technology, and can give a gift to millions, 25 million people around the world that cannot move any longer because of a spinal cord injury.

They're going to go down across your corpus callosum, down onto your spinal cord to your lower motor neuron out to your muscles here, and that electrical discharge is going to be picked up by these electrodes right here and we're going to be able to listen to exactly what your brain is going to be doing.

So right here, these are the motor units that are happening from her spinal cord out to her muscle right here, and as she's doing it, you're seeing the electrical activity that's happening here.

This is the front of the brain, the back of brain with the spinal cord hanging down, and this is how it would be positioned inside of my head.

Its antler penetrated my trachea and my esophagus and stopped at my spinal cord and fractured my neck.

These detectors are specialized nerve cells called nociceptors that stretch from your spinal cord to your skin, your muscles, your joints, your teeth and some of your internal organs.

Well, when you get hurt, special tissue damage-sensing nerve cells, called nociceptors, fire and send signals to the spinal cord and then up to the brain.

The superhighway that carries pain information from the spinal cord to the brain is our sensing pathway that ends in the cortex, a part of the brain that decides what to do with the pain signal.

Over time, this causes wear and tear in your spinal discs, overworks certain ligaments and joints, and puts strain on muscles that stretch to accommodate your back's curved position.

Indeed, we designed it together with neurobiologists to understand how animals move, and especially how the spinal cord controls locomotion.

Then you have the spinal cord, and in the spinal cord you find reflexes, multiple reflexes that create a sensorimotor coordination loop between neural activity in the spinal cord and mechanical activity.

These are very interesting circuits in the spinal cord of vertebrate animals that can generate, by themselves, very coordinated rhythmic patterns of activity while receiving only very simple input signals.

And these input signals coming from descending modulation from higher parts of the brain, like the motor cortex, the cerebellum, the basal ganglia, will all modulate activity of the spinal cord while we do locomotion.

But what's interesting is to what extent just a low-level component, the spinal cord, together with the body, already solve a big part of the locomotion problem.

You probably know it by the fact that you can cut the head off a chicken, it can still run for a while, showing that just the lower part, spinal cord and body, already solve a big part of locomotion.

Now, understanding how this works is very complex, because first of all, recording activity in the spinal cord is very difficult.

It's much easier to implant electrodes in the motor cortex than in the spinal cord, because it's protected by the vertebrae.

So what we do in my lab is to collaborate with neurobiologists like Jean-Marie Cabelguen, a neurobiologist in Bordeaux in France, and we want to make spinal cord models and validate them on robots.

Now, one thing which is very surprising and fascinating in fact is the fact that all this can be generated just by the spinal cord and the body.

Just changing the global drive, as if you are pressing the gas pedal of descending modulation to your spinal cord, makes a complete switch between two very different gaits.

If you stimulate the spinal cord of a cat, you can switch between walk, trot and gallop.

And this really shows that the spinal cord is a very sophisticated locomotion controller.

So let's go to the spinal cord.

So here what we did with Jean-Marie Cabelguen is model the spinal cord circuits.

So what you see here is a previous version of Pleurobot that's completely controlled by our spinal cord model programmed on board of the robot.
