Wednesday, November 15, 2006 - 10-11 AM, S-5 Osmond Building

Speaker: Jian-young Wu, Professor, Department of Physiology and Biophysics, Georgetown University in Washington, DC

Dr. Wu is one of the world's leaders in optical imaging of the nervous system. His work is of broad interest to the Science and Engineering community at Penn State.

NOTE: This seminar will be available as an open broadcast to the Penn State community at:

You will need a sound card and speakers to view this properly. We are working to improve the audio. This broadcast will be available in room H4151 at Hershey.

Please join Dr. Wu for lunch afterwards, if interested.

In neocortex, population neuronal activity is organized as propagating waves. Propagation direction and velocity of the waves may play a role in organizing cortical activity for brain processing. I will start with a brief introduction of how waves of neuronal activity in neocortex can be visualized with voltage-sensitive dye imaging. Then I will show several wave patterns (e.g., spirals) generated in neocortical slices and their functional implications. In the last part of my talk I will show new data of in vivo imaging, in rat whisker barrel cortex and visual cortex.
