5.Some people are like homing pigeons:Drop them off anywhere,and they'll find their way around.Other people,though,can't tell when they're holding a map upside down.Are the directionally challenged just bad learners?
Not all of your navigational (导航的)skills are learned.Research shows that your sense of direction is innate.An innate ability is something you are born with.Your brain has special navigational neurons-head-direction cells,place cells,and grid cells (网格细胞)-and they help program your inside compass when you're just a baby.
In 2010,scientists carried out an experiment to study baby rats'neural activity in their brains.Although the rats were newborns,the researchers discovered that their head-direction cells (which help them recognize the direction they're facing) were fully grown and developed.The rats,it seemed,were born with a sense of direction.And they hadn't even opened their eyes yet!
Humans,of course,are not rats.But the hippocampus-the brain area we use for navigation-is similar in most mammals.If the rat's compass develops this way,then it's likely that a human's compass does,too.
If we're born with a sense of direction,then why are some people so good at getting lost?The scientists found that the two other cells-place and grid cells-developed within the first month.Place cells are thought to help us form a map in our mind,while grid cells help us navigate new and unfamiliar places.The two cells work together,and that's where the trouble might be.
People who took part in a 2013 study played a video game that required them to travel quickly between different places.Monitoring their brains,the scientists found that grid cells helped the gamers recognize where they were-even without landmarks.According to researcher Michael Kahana,differences in how grid cells work may help explain why some people have a better sense of direction than others.

A.Rats have a natural ability to recognize directions.
B.Rats'hippocampus is different from that of humans.

C.They help us use a compass when we lose our way.

C.They are unfamiliar with new places.
