Vice President John W. Colloton To Retire Dec. 31 After 44 Years At UI John W. Colloton will retire Sunday, Dec. 31, 2000 after serving in various roles at the University of Iowa over the past 44 years. Colloton has served in his current position, University Vice President for Statewide Health Services, since July 1, 1993. Colloton is internationally recognized for visionary leadership as director and CEO of the University of Iowa Hospitals and Clinics from 1971 to 1993. He is credited with developing the strategic concept and marshalling the resources — both human talent and monetary support — that enabled the University of Iowa Hospitals and Clinics to develop from an institution whose service role was almost entirely indigent patient care into one of America’s premier teaching hospitals.

ST. LOUIS POST-DISPATCH, Dec. 28 -- A recent University of Iowa study is the first to investigate human emotion processing by the right prefrontal cortex at the level of individual brain cells. "This kind of single-cell study is very rarely performed in humans," said RALPH ADOLPHS, Ph.D., assistant professor of neurology and principal investigator on the study. The findings appear in the January issue of the journal Nature Neuroscience. In addition to Adolphs, other UI investigators involved in the study included HIROTO KAWASAKI, M.D., post doctoral fellow in neurology, MATTHEW A. HOWARD, M.D., associate professor of surgery and neurology and ANTONIO R. DAMASIO, M.D., Maurice Van Allen Professor of Neurology and head of the department.

YAHOO! NEWS, Dec. 28 -- A new University of Iowa study gives a rare glimpse of human brain cells in action as they respond to emotionally stimulating images. In the January 2001 issue of the journal Nature Neuroscience, the UI neurologists took advantage of a rare clinical opportunity to get up close and personal with specific brain cells in an awake, alert human. A 48-year-old man was being prepared for neurosurgery in hopes of treating epileptic seizures that had not responded to medication. To isolate the exact region of the brain that was causing the seizures, epilepsy surgeon Dr. MATTHEW HOWARD inserted two depth electrodes into the patient's brain to monitor seizures and pinpoint the problem. While the electrodes were in place, the researchers showed the man happy, neutral and aversive images, the latter including disturbing images of mutilations and war. Howard and his colleagues were stunned to find that while the happy and neutral images provoked little immediate response, the aversive images provoked reactions in as little as 0.12 seconds, probably faster than the patient was consciously aware of the image.

NEWSDAY, Dec. 26 -- KEVIN KELLY, an anthropologist at the University of Iowa, is the co-author of a never-published letter of protest to the journal Nature regarding a controversial study by University of Auckland researchers Russell Gray and Fiona Jordan, who borrowed a method commonly used by evolutionary biologists to compare the DNA of related organisms and adapted it to compare the words of related Austronesian languages. "I have no problem with using these methods," Kelly said of Jordan and Gray's evolutionary biology approach to language trees. "The one thing that troubles me is that I feel that the lab people are thinking they're going to come in and rescue anthropologists by using these methods," an approach he finds patronizing. "But a lot of times they fall into the same circular arguments that the anthropologists have fallen into."
