The Center for Consciousness Studies at the University of Arizona is running a webcourse on consciousness, directed by Bernard Baars and Katharine McGovern, from June 12 to September 25 this year. It should give an excellent background in the field (especially on the cognitive science side) for people who don't have courses like this at their own university, or who are outside the academic system. The rates are pretty reasonable, especially if you register by May 25.
Plans are also well underway for the next Tucson conference on Toward a Science of Consciousness, to be held April 4-8, 2006. Speakers will include Antonio Damasio, Paul Davies, Walter Freeman, Douglas Hofstadter, David Rosenthal, Oliver Sacks, John Searle, and many others.
