　　Up next today, according to the Centers for Disease Control, it's something that kills more thannine people in the U.S. every day and injures more than 1,100 nationwide. Car crashes when adistracted driver is reportedly involved.

　　Now, many people will hear that and think texting.

　　But distractions far simpler than messages can keep the brain from focusing on the road.

　　We often take driving for granted, until something goes wrong, and then we think, what werewe thinking?

　　Because driving involves your hands, your feet, your eyes, your ears, but it's the brain thecontrols the action.

　　In fact, driving uses about 20 different parts of your brain and distracting even one of thoseand the job at hand can be dangerous.

　　Let me show you what I mean:

　　everything you'll see while driving is handled here by the occipital lobe, while the temporal lobeinterprets the sounds that you hear.

　　So, taking your eyes off the road or turning off the music can really affect that input.

　　You see that was close.

　　Measuring distance between cars changing lanes, deciding on how to stop, that's a job of aparietal lobe.

　　It integrates data from all of your senses.

　　It's activated when you switch your attention from one thing to another.

　　But it too can be easily distracted.

　　For example, just listening to someone talk reduces the activity of the parietal lobe by nearly 40percent.

　　That affects how you drive.

　　While talking on the cell phone and driving, even with an earpiece, that was said by researchersto be a recipe for disaster, especially if you're turning in to oncoming traffic.

　　I bet you're thinking.

　　So, if the brain needs to focus so much, why does driving seem so automatic?

　　Well, it's you've imprinted those motor skills in your brain is part of procedural memory.

　　It's your brain on autopilot.

　　It allows you to focus on the more important things, like getting home safely.

　　It's time to test your geographic genius.

　　What country's capital is Accra?

　　If you said Ghana, a nation in West Africa, you got it.

　　And we're glad to have the students of Ghana International School watching CNN STUDENTNEWS.
