Current Events 8: Human brain has more switches than all computers on Earth

Don't ever think that your brain is a simple thing.
Some new research by Stanford students has found that there are more switches in the human brain than all the switches in every computer on earth added up.
In you brain, there are things called nerve cells, or neurons. Those are hard to define, but I found that they are "cells that are specialized to conduct nerve impulses". In other words, they are the controllers of the nerves in your body. If you didn't remember what nerves were, let me remind you: nerves are the things in you body that control you feelings (pain, hunger etc.), and they also help you control you movements. 
Back to neurons: you brain has 200 billion of them. They are connected together with 100s of trillions of synapses. Synapses are basically just connections between the neurons. (I know this is a lot of vocab for one post!) Although not every neuron is connected to every other neuron, that's still a lot of synapses. In order to fit so many synapses into your brain, they are extreme small. They're less than one-thousandth of a millimeter wide each. All of this was discovered by students in the Standford University School of Medicine. They were creating a new imaging model, in other word a new way to scan and represent the brain. They call their new model array tomography. Array tomography can be used with some computer software that can make a 3d image of the synapses in a brain. When the Stanford researchers  created this model, they were amazed by how complex the brain is. Just look:

This was my hardest current events ever. I didn't even understand the article myself when I read it, and there were seemingly millions of terms to look up.
