Competing Interests

CT, KD, and SLD have stock in Circuit Therapeutics Inc, which has licensed a patent related to this work (Materials and approaches for optical stimulation of the peripheral nervous system; serial number 61/079,035; file date 7/7/08), but provided no support to this work. CT is an employee at Circuit Therapeutics Inc, where KD and SD are also consultants. This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials.
