Last year Ponce School of Medicine organized an international conference on extinction learning, held at the Ponce Hilton. A special issue of Biological Psychiatry devoted to that conference has just come out, Ponce Vejigante and all. Visit Biological Psychiatry Journal at http://journals.elsevierhealth.com/periodicals/bps for more information. This conference was funded in part by the UPR COBRE Program, and NIMH.
