Well, that leads us nicely into our presidential symposium entitled, Brain Isolations, Good and Bad Vibrations. I could not think of a better song to introduce this being on Southern California and the title of our symposium. So, before introducing the speakers, I just want to make a few comments required to do. It’s the policy of the American Epilepsy Society that all faculty participating in continuing medical education are expected to disclose to the audience any ... or current conflicts of interest related on the context of the activity. Faculty that the disclosures have been made in writing and can be found in your handout. Please do not forget to use the online program to evaluate this programs since obtain in your CME and CE credit. The instructions are in the program book in each program handout. The handout packages of all the slides from today’s presentation were distributed at the door.
 So at this point we can just introduce, I was going to have a slide of the speakers but that's okay. We're going to have four speakers today. We're going to start of with an introductory talk in Pete Engle is going to speak on Oscillitations in Limbic Epilepsy. Okay, good. For those who did not know, Pete is at UCLA and knocked UST at the championship game yesterday, he’s very happy. That’ll be followed by a talk by Professor Ben-Ari who is going to talk on High-Frequency Oscillations are Needed for Seizures to Beget Seizures in the Developing Brain. Then, Bob Muller from the State University of New York in Brooklyn is going to talk about the How the Activity of Place Cells Reveals the Nature of Hippocampal on Pathology. And we’re going to finish the sessions with John Huguenard who’s going to speak on Oscillations in the Thalamocortical System: Mechanisms of Epileptic Synchrony. So, I'd like welcome Pete up to the podium and Pete will be moderating the session or we’re going to try to do depend upon time as he take some questions at the end of the session if there is a time. So please stick around if you have the free time then to ask some questions. So, Pete welcome.
