Diffusion Tensor Imaging

By Emily Singer This article is the sixth in a series of 10 stories we're running over two weeks, covering today's most significant (and just plain cool) emerging technologies.

It's part of our annual "10 Emerging Technologies" report, which appears in the March/April print issue of Technology Review.Flipping through a pile of brain scans, a neurologist or psychiatrist would be hard pressed to pick out the one that belonged to a schizophrenic.

Although schizophrenics suffer from profound mental problems - hallucinated conversations and imagined conspiracies are the best known - their brains look more or less normal.

This contradiction fascinated Kelvin Lim, a neuroscientist and psychiatrist at the University of Minnesota Medical School, when he began using imaging techniques such as magnetic resonance imaging (MRI) to study the schizophrenic brain in the early 1990s.

Lim found subtle hints of brain structures gone awry, but to understand how these problems led to the strange symptoms of ba href=/schizophrenia/a/b, he needed a closer look at the patients' neuroanatomy than standard scans could provide.

Then, in 1996, a colleague told him about diffusion tensor imaging (DTI), a newly developed variation of MRI that allowed scientists to study the connections between different brain areas for the first time.[For a view of diffusion tensor imaging, click here.] Lim has pioneered the use of DTI to understand psychiatric disease.

He was one of the first to use the technology t...

With the success of the showing the two have paired up again to produce “What Happy Faces are Hiding” on April 18.

The event will bring Ross Szabo to campus to discuss depression among college students.

Support groups are also encouraged as an outlet for students, with a current one starting today about Aspergers Syndrome.

[See “Aspergers” to the right of this page.] “If the students run [the group] there is more success,” Oakes said.

While DSS is equipped to accommodate students in a learning environment, their involvement with students also blends with that of facilities management.

Physical accommodations are handled by American Disability Act Compliance Officer Scott Guckert, who works separately from DSS, but has teamed up with the office in certain instances.

“Sometimes what’s compliant for one student is not for another,” Willemin said.

“Accommodations aren’t one size fits all.” Hands on Help: Services, Resources Available at Disability Support Services Post your feedback on this topic here Date Subject Posted by: No feedback has been posted yet.

Ordinary voices

...ba href=/schizophrenia/a/b," says former foreign minister Surin Pitsuwan."The current wave of demonstrations can be seen as a symptom of a suffering psyche, dislocated by over- consumption, unbalanced by over- ambition, a psyche that is yearning for a proper balance that can only be achieved by a wise leadership.

For what is raging on the streets is not what we see at first sight.

It reflects a deeper malaise that is eroding the Thai sense of well-being altogether.

Uncomfortably for observers and participants in this drama is that labels of left and right wing, of democrat and autocrat, do not sit easily on any side.

Noi the cleaner wants to vote.

Chotima and Sopida and most protesters want the King to intervene.

The Democrat Party boycotted the election "to save democracy." Hard-line former policeman Thaksin says he's defending the right of the people to vote against rule by mob.Few are talking about other issues.

There is no mention of Thaksin's dangerous human rights record, or his "War on Drugs" which saw at least 2,000 people gunned down in cold blood.

Nor is there talk about the ongoing conflict in the south, where people are dying every day in a conflict between separatists and a heavy-handed police and military establishment.The challenge is that: "The current administration has made corruption and political favoritism legal and it is fair to say that state officials at all levels, whether directly involved in the process or not, have accepted it as a natural phenomenon that no o...
