Brain cell

The human brain is the most complicated organ that nature has ever created: 100 billion nerve cells and many more contact points between them provide our brain with capabilities that no supercomputer can match to this day. One of its most important characteristics is its ability to learn. But how can a collection of neurons learn anything in the first place?
