The adult human brain has about 100 billion cells, each one of these having the ability to connect to tens of thousands of others. How this marvelous organ in our body, that shapes our thoughts and our lives, functions, has still not been understood exactly, but scientific research continues to unravel many of its mysteries.

1. Your brain isn’t very good at multi-tasking. When you’re trying to do more than one thing at a time, your brain is not really working on several fronts simultaneously; instead, it’s rapidly switching from one task to another and back. That’s why multi-tasking is not a very efficient way of working.

2. Size doesn’t really matter. Bigger brains do not necessarily mean you’re smarter. Actually, our cave-dwelling ancestors had much bigger brains (and bodies) than us, but with evolution, the processes going on in the human brain became more complex and IQ levels climbed higher. Forensic examination of Albert Einstein’s brain after his death revealed that it was actually smaller than average!

3. Meditation makes you smarter. At least, it definitely improves your ability to focus and make better decisions. Scientific studies involving Buddhist monks showed that the parts of the brain that help concentration and decision-making were more developed because of their regular routine of meditation.

4. The left side of your brain controls the right side of your body. And vice-versa. This is true of all humans, whether left or right-handed. That’s why if you suffer from a stroke that affects the left side of your brain, limbs on the right side of your body may become paralyzed.

5. The more you use it, the more you sharpen it. Just like any other part of your body, your brain also needs exercise, or it becomes ‘rusty’. Curiosity may be the greatest asset you have, because learning new skills and mastering mental tasks makes the connections between brain cells stronger.
