Love On My Mind
By Elizabeth Werhane '00
Edwinn Starr asked, “War, what is it good for?” but Stephanie
Ortigue has posed a new question: Love, what is it good for?
Ortigue, head of the 4D Brain Electrodynamics Laboratory, tests how love affects
the brain. She conducts her research under the umbrella of the University of
California, Santa Barbara’s Brain Imaging Center. Although Ortigue’s
studies are ongoing, her testing suggests that love is good for the brain.
"I try to understand some of the most complicated experiences in our
daily life,” Ortigue said. “Love is one of the most important questions
to study.”
The Brain Imaging Center has become a hub for brain studies with the addition
of the 28,000-pound fMRI machine that arrived on campus in June 2007. An MRI
machine generates images of the brain. The f stands for functional; you can have
someone in the machine complete a task and see what part of their brain becomes
activated.
The fMRI data creates a comprehensive map of where brain activity happens,
showing three-dimensional images of the brain. Researchers also collect data
from the university’s Geodesic EEG system, which provide data on when activity
happens in the brain. Combining the two ñ with the when and the where
information — gives researchers a four-dimensional look at the operation
of the brain, making it easier to see correlations between cause and effect.
To begin her tests, Ortigue had to find people in love. Volunteers who stated
they were in love completed the Passionate Love Scale questionnaire, a series
of questions created by Elaine Hafield in 1986 to determine whether someone meets
psychology’s definition of love.
The survey asks them to rate statements on a scale of one through nine, with
one meaning ìnot at all” and nine meaning ìdefinitely.” Examples
include “I would rather be with _____ than anyone else.” And ìI
have an endless appetite for affection from _____.”
The Swiss National Foundation initially funded Ortigue’s research when
she was at Dartmouth. She’s now applying for other sources of funding.
When Ortigue conducted similar studies at Dartmouth in previous years, she
exclusively tested women subjects. After coming to UC Santa Barbara in October
2006, she extended it to men. “It was pretty hard to find men in love on
campus,” Ortigue said, but she found that some exist.
Even before enrolling subjects, Ortigue’s test plan went before the
Human Subjects Committee, which conducts an ethical review.
Kathy Graham, research personnel analyst for the Human Subjects Committee,
said the fMRI itself has minimal physical risk ñ as did Stephanie’s
test overall. “Whether someone is in love or not in love is not going to
increase the risk to the individual,” Graham said.
In her study, subjects in love and not in love were placed in the fMRI machine.
They watched a display area, where the name of the person they were in love with
might be presented subliminally — so fast that their brain couldn’t
consciously read the name. They were then asked to do a “lexical decision
task.” They would be shown an arrangement of letters quickly, and then
they had to determine whether it was a real word or not.
Ortigue found that when people were really in love, they were faster to do
a task if their love’s name had been subliminally presented. She may conduct
similar tests using subliminal images of the face of the person the subject loves.
Ortigue expanded her studies to examine whether loving something had similar
effects to loving someone. In collaboration with Dr. Francesco Bianchi-Demicheli,
a Swiss psychiatrist, she developed a variation of Hatfield’s questionnaire
called the Passion Scale. The Passion Scale gauges how enamored someone is with
a particular hobby or activity, such as music or surfing.
In tests of loving someone or loving something, the part of the brain activated
by love is in the angular gyrus — a portion of the brain approximately
above the left ear. It’s an area of the brain associated with self-representation
as well.
With the fMRI machine in the basement of the psychology building, UC Santa
Barbara is well equipped to peek into the mind. The fMRI on campus has a 3-tesla
magnet, returning higher spatial resolution than most hospital MRI machines,
which typically have a 1.5-tesla magnet. ìIt gives you a very nice picture
of your brain,” Ortigue said.
The MRI, a Siemens Magnetom Trio, can take a picture of the brain in as few
as four minutes. In tests that ask subjects to perform a task, someone can be
in the fMRI for up to two hours.
As stewards of this research tool, the Brain Imaging Center, led by Director
Scott Grafton, collaborates with other scientists to learn about the brain.
The Parkinson Association of Santa Barbara teamed up with Ortigue to study
whether love can improve reaction times. Parkinson’s patients, often characterized
by their decreased motor functionality, stand to benefit from activities that
help the brain react faster. In the past six months, Ortigue tested 12 patients ñ both
on and off medication ñ and although testing is not complete, she said
she’s seen promising results.
Ortigue’s not talking much about applications of her studies yet, although
she hints that if there’s a way to re-create the brain activity of someone
in love, it might be possible to reap the benefits of love without being in love.
She’s also not talking on the question of whether she has a significant
other. She doesn’t wear a ring, and she limited her confession to a coy “I
am in love with neuro science.”
What’s next? “I want to see if love can improve creativity,” Ortigue
said.
