Life Sciences Seminar Series
|Associate Professor of Integrative Physiology and Neuroscience, Department of Biology and Wildlife, Institute of Arctic Biology, UAF|
|Title:||To Breathe or Not to Breathe|
|Date:||Friday, 26 September 2014|
|Location:||Murie Life Science Bldg, Murie Auditorium.|
This presentation will review the central elements of my research program, directed at understanding the cells and mechanisms critical to the control of breathing. A primary focus of my work are the mechanisms by which the brain responds to changes in CO2/pH (central chemosensitivity) and the functional consequences of dysfunction to elements of this control system. This work incorporates investigation at multiple levels of reduction from organismal to cellular approaches, and is focused on cellular mechanisms and network interactions between critical neurons within the brainstem. Brainstem dysfunction is associated with enhanced vulnerability to the Sudden Infant Death Syndrome as well as a number of other severe pathologies. An overarching hypothesis is that specific neurons are necessary for a number of homeostatic reflexes and that dysfunction compromises critical reflex responses, such as central chemosensitivity. My research addresses: 1) basic mechanisms of chemosensitivity; 2) functional consequences of raphé dysfunction with the potential for development of diagnostic tools to identify vulnerability to SIDS and other disorders; 3) mechanisms of functional recovery from raphé system damage or dysfunction. My work also encompasses investigation of the potential evolution of critical homeostatic mechanisms, and the evolutionary origin of breathing in vertebrates.
