Title: The ups and downs of a teenage brain.

Date: November 2011

Summary:

The ups and downs of a teenage brain proves that what scientist thought about a

person’s IQ never changing, is probably not true. In this study, neuroscientists from

The University College London, used 33 teenagers from ages 12-16 years old and

gave them and IQ test and also took and MRI of their brain (which is a picture).

They started the study in 2004 and then three or four years later they brought back

the same 33 students. When the students came back they took another IQ test and

had another picture of their brain taken.



This study found that a teen’s IQ can change. They found that some IQs got higher

and some got lower. Along with the change in IQ scores, the scientists also found

that the gray matter in some of the teens brains had increased, which means more

brain cells. The scientists think that a possible reason for the increase in IQ, could

be from socializing and sports.
Opinion:

I think this article is interesting that some of the IQs went up and some went down,

when they thought they wouldn’t change. I was fun to learn about new facts and

words.



Fields of Science:

Neuroscience- the study of the brain and nervous sytem
