BUFFALO, N.Y. -- Richard J. Traystman, Ph.D., recognized internationally for his discoveries involving brain circulation and metabolism, will present the 10th annual Hermann Rahn Memorial Lecture at 4 p.m. on Oct. 25 in Room G-26 of Farber Hall on the University at Buffalo South (Main Street) Campus.

Traystman is distinguished research professor, senior vice chair for research and director of anesthesiology and critical care medicine laboratories at The Johns Hopkins University. His lecture topic will be "Mechanisms of Brain Injury Following Ischemia, and Mechanisms of Neuroprotection." Sponsored by the UB Department of Physiology and Biophysics, the lecture will be free and open to the public.

The lecture series honors Hermann Rahn, pre-eminent scientist and physiologist, who was instrumental in defining many of the principles of respiratory physiology. Rahn was a SUNY Distinguished Professor in the UB Department of Physiology and served as chair of the department from 1956-73. He died in 1990.

Traystman, who serves on the editorial board of several journals, has received widespread acclaim for his research into the effects of chemoreceptors, baroreceptors, sympathetic nerves, hypoxia, hypercapnia and drugs on regulation of cerebral circulation. His studies of gender differences in brain ischemia and the role of estrogen as a neuroprotector are considered seminal.

He also has made substantial contributions to understanding the physiology of heart-lung function. His research in this area has included studying mechanisms that regulate pulmonary collateral ventilation and development of more effective ways to apply cardiopulmonary resuscitation, or CPR.

The National Institutes of (NIH) has supported Traystman's research for more than 30 years, and he currently directs a NIH program project grant. He has received many honors and awards, and has served on numerous research and advisory committees at the NIH, the American Physiology Society and the American Heart Association.
