10 Mysteries of the human mind

Our brains hold a lot of secrets that not everyone totally understands. But that's the exciting thing about some of its mysteries! Here's a list of 10 interesting elements involving the human mind that are not fully explained.

For example, have you ever heard the term "phantom limb?" This references the sensation amputees can relate to when they lose a body part. Specifically, it means they can still feel their missing attachments. A startling number of amputees are estimated to feel itching, pressure and even pain -- on in regards to limbs that don't exist. Why is this? They think it's because the brain is hard wired to function as a whole body, so it acts like a blue-print.

Another "mystery" is the understanding of laughter. Researchers can't quite pin down why people laugh! For instance, why would some people laugh at slap stick humor while others get a rise out of horror movies? They know three areas of the brain are involved with laughing, but the cause underlying this whole effect is still unknown! Check out the rest of the tidbits here.
