What's the difference between a mutant neuron, or nerve cell, and an ordinary one? This amazing time-lapse video from MIT shows two neurons developing into healthy and weird variants.

The one on the right is the mutant. On the left, the cell is sending out healthy dendrites and trying to connect to other nerve cells.

There's really nothing more fascinating than watching neurons develop - they are the building blocks of thought in your brain, and in this video you can see fetal neurons developing, growing connections between one another. In a brain, those connections could literally form thought-associations and memories.

Just a couple of weeks ago, Georgia Tech released a brand-new video of neurons firing. Electrical signals hop from one neuron to the next, lighting up each cell as the signals move. When neuroscientists do fMRI images of brains, they are looking to see which parts of the brain have become engorged with blood, because those are also the areas with the greatest electrical activity. EEGs look directly for electrical signals. Looking for electrical activity in the brain has allowed scientists to figure out where we process information related to memory, facial recognition, desire, and many other things.
