Wendy, If by chance you talk to Neal Castagnoli Jr. who is an old school friend of mine. I lost track of him over the years. His name appeared in Dr. Langston's new book " The Case of the Frozen Addicts". Give my Email address to him, I would like to get some mail from him. His talk on monday titled: Dopamanergic Neurotoxicity: Chemical and Biological Requirements - Thanks, Jon Stedman
