Description:
Patolsky et al. (Reports, 25 August 2006, p. 1100) used silicon nanowires to record action potentials in rat neuronal axons and found increases in conductance of about 85 nanosiemens. We point out that the data correspond to voltage changes of about -85 millivolts on the nanowire and that conceivable mechanisms of axon-nanowire interaction lead to signals that are opposite in sign or smaller by orders of magnitude.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fromherz, Peter -- Voelker, Moritz -- New York, N.Y. -- Science. 2009 Mar 13;323(5920):1429; author reply 1429. doi: 10.1126/science.1155416.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Membrane and Neurophysics, Max Planck Institute for Biochemistry, D82152 Martinsried/Munich, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19286538" target="_blank"〉PubMed〈/a〉
