    This simple ratio was once thought to be a measurement of intelligence. But using this as a metric, birds would be smarter than humans, and humans would have the same intelligence as a mouse.

    True!

    Pain receptors, or nociceptors, are nerve cells that send pain signals TO the brain. The brain itself doesn't actually have any. This is why open brain surgery can be performed when a patient is conscious.

    True!

    It's true! Even more remarkable is the fact that it accounts for only 2% of our body weight.

    Correct!
    Wrong!

    True!

    It's actually a rare medical procedure called a hemispherectomy. The brain is remarkably adaptable and it can rewire its functions in a way that allows it to operate with only one hemisphere.

    Correct!
    Wrong!

    False!

    Sure, there has been some promising work using fMRI scans to visualize thoughts as they happen in the brain, but calling it "mind-reading" would be overselling it.

  7. 7.

    Correct!
    Wrong!

    True!

    Short term memory exists in the lateral prefrontal cortex and the hippocampus, whereas long-term memory generally exists in the neocortex.

  8. 8.

    Correct!

    False!

    The brain is a lot more complicated than this simple myth would suggest.

    Correct!
    Wrong!

    True!

    This is true for most people. That being said, it is possible for the right side to develop the same skills (in the case of a hemispherectomy, for example).

  10. 10.

    Wrong!

    False!

    This is a widely cited number, but no peer-reviewed studies have actually shown it to be true. One study estimates that there are around 86 billion neurons in the brain.

  13. 13.

    More accurately, alcohol PREVENTS the brain from making NEW memories.

    Correct
    Incorrect
    Correct!
    Wrong!

    False!

    Up until 1998 that's what science thought, too. But we now know that new brain cells can be generated in adults.
