With an average weight of 1.36 kilograms, the human brain is truly something to marvel at. It is difficult to believe that something akin to a malformed sponge at first glance, contains over 100 million neurons and 100 trillion synaptic connections. As far as we know, it is the single most complex unit in the universe. Indeed, an organ as intricate as our brain will no doubt be riddled with its fair share of problems. This list deals with 10 people who have experienced just that; a part of their brains has gone awry in some form or another. I hope that after reading this list, you will gain a deeper appreciation about the inner workings within your own brain, and come to understand the importance of keeping it safe and sound.
