Picture of a Thought

If you thought the network that makes up the internet was complicated, then spare a thought for scientists who study the brain. The 6 billion plus devices that are connected by the internet are dwarfed in comparison to the brain which has ten times the number of neurons.

Slice up a brain in to thousands with a powerful magnetic field and you get fMRI - functional magnetic resonance imaging which allows us to see activity in the brain. You can also measure brain activity with EEG – (Electroencephalography). If you want EEG and fMRI explained a lot better and a lot easier than this, then take a look at this video, produced by Sciencenordic with animation by Per Byhring.
