What
is our goal?
We
are conductiong a study of brain functioning as it pertains to language
and reading tasks. Our goal is to better understand children with and without
reading disabilities. We also hope to see how intensive instruction affects
brain function.
Who
can help us?
Your
child can help if they are between the ages of 8 and 12, and are native
speakers of English. They must be in good mental health and not have any
ferrous metal (iron) in their body.
What
kinds of metal are ferrous?
There
are some possible metal items that would restrict your child from participating,
like dental braces or a permanent retainer. It is okay if your child wears
glasses with metal frames, because we can provide prescription glasses
with plastic frames just as a "loaner" during the scan. Zippers on pants
are fine. Here is a more complete list of types of metal that would disqualify
someone from participating.
permanent
dental retainer |
metal
fragments in the eyes |
cardiac
pacemaker |
dental
braces |
aneurysm
clip |
neurostimulator |
cochlear
implant |
|
shrapnel |
Are
some kinds of metal OK?
Anything
non-ferrous is safe. We have a magnetic detector here to check if there
is any doubt.
What
will my child be asked to do?
Children
will perform reading tasks presented on a computer screen. For example,
they will be asked whether two words rhyme. They will also have an
fMRI scan while they do these reading activities. Your child's appointment
will last approximately 2 to 3 1/2 hours. Most of the time is just to let
your child become familiar with the reading activities.
How
long will my child be in the fMRI?
You
child will be in the fMRI scanner for about 50 minutes.
What
exactly is fMRI?
Functional
Magnetic Resonance Imaging is a safe, non-invasive technique. It does
not involve any x-rays or injections. fMRI allows us to determine what
areas of the brain are working while a person reads a word or a sentence.
An fMRI scan involves lying on a table, which slides part way into the
scanner. When in the scanner, children will perform computer reading exercises
while their brain activity is recorded.
