The Third Brain Matters Conference will be held on October 24-25, 2012 in Cleveland, Ohio. From the website: "Continuing the tradition of Brain Matters conferences held in 2009 and 2011, this conference is designed to support and stimulate the emerging field of neuroethics. A primary theme will be ethical dilemmas posed by conditions without an identifiable biological correlate in both research and clinical settings."
The organizers are currently accepting abstract submissions which may address a wide variety of topics related to neuroethics, including topics unrelated to the conference theme. The deadline is May 15, 2012. See here for further information about the conference and abstract submissions.
