EMPLOYMENT DEVELOPMENT GUIDED EXPERIENCE
Dress for Success
April 17, 6 to 8 pm • EMU Fir Room
Presented by Aramark
A one hour fashion show will demonstrate
appropriate interview and business casual attire
for men and women. Subsequent one hour men's
and women's workshops will then address
grooming and accessories, and will answer
questions.
Refreshments will be served.

fMRI
continued from page 5
technology since 1978.
“We know a lot about what parts
of the brain function,” he said.
“But we haven’t gotten to the point
of, say, an athlete who enhances
his body’s performance with prop
er care and training.”
Paul Dassonville is more con
cerned with how perception deter
mines reality. The assistant psy
chology professor has been at the
University for three years and has
worked with fMRI machines for
six years.
“My main research line relates
to using the fMRI in studying the
pattern of brain activity that cor
responds with different types or
levels of perceptual awareness,”
he said.
Dassonville said he plans to con
duct a study in which he will
show a variety of digitally project
ed images to subjects and evaluate
their brain activity. For example, a
person lying with their head in the
fMRI might see a picture of a face
followed by a scrambled image.
The subject must identify which is
a face and which is scrambled as
the images quickly change.
This activity will help Das
sonville pinpoint which regions
of the brain the subjects use to de
termine what they think they saw
versus what’s actually shown.
Dassonville said he hopes the
findings will help psychologists
and students better understand
what happens when the brain
perceives the world.
“The research and knowledge
we’re gaining will be passed on to
students as we teach,” Dassonville
said. This term he is teaching an
upper-division psychology course
in perception.
The fMRI is similar to a magnet
ic resonance imaging machine, or
MRI, but is much more powerful.
It is a shallow tube of sensors that
can pinpoint minute locations in
the brain and measure differences
in brain activity based on blood
flow to those locations. In short,
the machine produces a magnetic
field that alters the natural arrange
ment of positively charged sub
atomic particles in the blood.
“If you have two magnets on a
table, and one is near the other
one, one spins and the poles
align,” technician for MR Imaging
Associates Scott Watrous said.
“Hydrogens, for example, line up
with a big magnetic field created
by the MRI scanner.”
Using high-tech computer soft
ware, researchers can detect radio
signals emitted from the protons
and translate them into an image
depicting a slice of tissue. They
can also measure how much time
it takes the disturbed particles to
settle again, and, based on the du
ration, can differentiate between
brain functions.
Linton said there’s a buzz about
the new fMRI in scientific circles
on campus. He expects more re
action as months stretch into
years, as hypothesis become the
ories and as research yields com
pelling answers.

U.S. Bank and the University of Oregon present
March s Star of Distinction...
ADAM
BERGQUIST
The U.S. Bank March 2002 Star of Distinction is Adam Bergquist, a senior from Boulder,
Colorado, majoring in exercise science and general science. Adam is a four-year
veteran of the cross country and track team and a scholastic star as well, with a
4.0 cumulative GPA. When he's not competing, he is an active participant in the
community, Adam recently made crafts with senior center residents and local
children through his service project with Mortar Board, and he assisted in building a
new home for a family in need through Habitat for Humanity.
U.S. Bank and the University of Oregon are proud to honor athletes who
demonstrate excellence in athletics, scholarship and community involvement —
Stars of Distinction like Adam Bergquist.
