Competing Interests

In the past 3 years, Dr. Weissman received investigator-initiated grants from GlaxoSmithKline, Eli Lilly & Co., and the Josiah Macy Foundation. These are no longer active and ended in 2007. She currently receives research funding from the National Institute of Mental Health (NIMH), the National Institute on Drug Abuse (NIDA), the National Alliance for Research on Schizophrenia and Depression (NARSAD), the Sackler Foundation, and the Interstitial Cystitis Association, and she receives royalties from the Oxford University Press, Perseus Press, the American Psychiatric Association Press, and MultiHealth Systems. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
