Guest lecturer in Biology is Nov. 13 Michael S. Hedrick from California State University, East Bay, will present a seminar titled "Development and regulation of the frog central respiratory oscillator" at noon Friday, Nov. 13, in 141 Starcher Hall. Hedrick received his M.S. in Biology from Portland Sate University and his Ph.D. in Zoology from the University of British Columbia. He is currently a professor and the chairman of the department of Biology Sciences at California State University, East Bay. The main project in his laboratory focuses on the development and regulation of respiratory rhythm generation, particularly in anuran amphibians. He uses an in vitro brainstem preparation from bullfrogs to investigate how respiratory rhythm is generated and regulated during devlopment. Everyone is welcome to attend. -- Dane Crossley, Assistant Professor, Biology, dane.crossley@und.edu, 777-4671
