Image of the Day

The images that appear in the "Image of the Day" are selected for the freshness of their views on Brain Mapping, their esthetic appeal, their quirkiness, or someimes just to prod you into thinking about the field and its context. Their appearance here is not an endorsement of their subject matter.

Daring To Take Risks and Reap the Rewards At the University of California, Los Angeles, Paul Thompson and his colleagues developed a novel computational framework that effectively stretches, contorts, and changes the geometry of highly image of Innovative brain-mapping techniquesdetailed three-dimensional brain images obtained via magnetic resonance imaging (MRI). These manipulations allow scientists to overlap and meld multiple brain images, collected over time or from multiple individuals, and enable comparisons between normal and dysfunctional brains. To date, the images have clearly revealed the changes wrought by Alzheimer's disease, methamphetamine abuse, schizophrenia, and AIDS. "With R21 funding, we developed new mathematical methods for understanding the effects of disease," says Thompson, an associate professor of neurology. "These images are really snapshots of a disease spreading over time."
