We see that as humans we are different from other modern primates, although we don't know exactly how that came to be. Unlocking this mystery has been Anthropology professor Carol Ward's life's work. While the fossil record is sketchy at times, it is crucial in estimating the chronology of certain key acquisitions of modern humans, be it walking on two feet, developing big brains, changing their diet, or changing their tool-making behavior. Working with fossils, Ward seeks to answer the bigger question—why did those changes occur?
In a back corner of the University of Missouri’s medical building, a few floors above the hospital and tucked away to the right, Habib Zaghouani watches a cellular war. He has been up there for seven years, with an army of graduate students and a colony of mice, trying to understand why our bodies attack us and how we can make them stop.
A rainbow of feathers floats upward like a psychedelic butterfly. Fingers of color, violet and lime green, seem to flow outward from the tips of the wings. If you didn’t know better, you might assume it is a work of art. Beyond their beauty, for Shawn Christ these images taken at MU’s new Brain Imaging Center reveal the brain’s activity and connections. In his role as Assistant Professor of Psychology and Director of MU’s Clinical Neuropsychology Laboratory, Christ studies how the relationship between the brain and behavior changes as we develop. Christ chose a career in psychology because it would combine two passions— working with kids and solving puzzles.
Collaborating with Mark Flinn (psychology and anthropology) and David Geary (psychology) on how and why human brains developed as they did.

Zaghouani’s third project has had great success. Cara Haymaker, who is in charge of this research program, reports that they have identified a successful treatment for experimental allergic encephalomyelitis, a disease affecting mice that is very similar to multiple sclerosis in humans. So far, the research team has been able to completely reverse the disease in mice with two forms of treatment.
The majority of Christ’s work focuses on the brain’s inferior frontal gyrus. That’s the part of the brain involved in most higher-level abilities: working memory, strategy use, inhibitory control, and especially keeping track of the to-do list for any sort of task.
Christ uses a lot of technology, including an eye tracker, projections, and functional and structural MRIs, to figure out why the brain works the way it does. All of these tools have their advantages and disadvantages.
