What’s Happening?

How Does This Work?

You might be wondering what being able to read someone’s brain waves has anything to do with being able to control their arm? Well, lets first see how our arm moves.

So we have around 80 Billion neurons in our brain which send signals from our brain to the rest of our whole body! To be able to move your arm specifically, something called a readiness potential occurs. It is a voltage that is measured at the motor cortex in your brain. Once that potential goes to a certain voltage, a synapse occurs in your brain. That then starts a response goes down your corpus callosum, down to your spine and then down to your lower motor neuron, then into the axons in your arm to the muscles which then trigger them to contract and that is what causes your arm to move.

Signals travel from your brain, all the way down to your arm through nerve cells, Nerve cells have long portions which are known as axons. They carry signals from your brain around your body. Nerve cells are very big. One nerve cell can be the size of about half of your body, this is why it is hard to repair them if they are damaged. Electrical signals are generated by the movement of ions, they are mainly sodium ions and are all positive cells which allow them to generate electricity. Electrical signals from your brain can travel at the speed of 150 Miles a second which is 540 kilometers an hour! We can also measure our muscle frequency by just putting electrodes on our arm.

Who Is Doing This?

However, when the patients, knew that they were detecting their subconsciousness, they were able to trick the computers by subconsciously thinking about moving a leg, the computer was able to pick it up and predicted it, but the patients knew what was going on, so they moved their arm instead, this is SO COOL! We as humans think we can’t control our subconsciousness and our decisions when we actually can and we can trick computers!

I don’t mean to confuse you, but then, the question becomes, when the patient tricked the computer, they were able to do it by thinking of something that they weren’t going to do, so would that be consciousness or subconsciousness? They were able to do it cause they controlled what they thought. However, subconsciousness is something a human can’t control. The computer was able to detect one’s subconsciousness” quote-unquote because then it would know that the person was going to move their arm in any given scenario as the human would always give a sign of what it would do.

So, that can only mean two things. One, the machine can predict subconsciousness and what will happen soon and the moment suppose 5 seconds later but can’t process in real-time on the spot to be able to know if the human changes its mind and the actions it will do. Or two, that we haven’t reached the potential to calculate subconsciousness and that we can only predict the consciousness of a person, even then, we can process it fast enough to predict changes in the mind of someone.
