Direct measurements of the individual steps cannot be made without destroying the mechanical structure; consequently, most measurements are taken downstream of the mechanical oscillations at locations like the auditory nerve. <br>Researchers Tim Gollisch and Andreas Herz have turned to computational methods and showed that it is possible to reveal the individual steps of complex signal processing by analyzing the output activity alone. Using grasshopper auditory receptors as models, the authors identified the individual signal-processing steps from eardrum vibrations to electrical potential within a sub-millisecond time frame and propose a model for auditory signaling. <br> <br>For more information, please visit: <br><a href="http://www.plosbiology.org/plosonline/?request=get-document&doi=10.1371%2Fjournal.pbio.0030026 " target="blank">www.plosbiology.org/plosonline/?request=get-document&doi=10.1371%2Fjournal.pbio.0030026 </a> <br></font></td> </tr> </table> </td></tr> </table> <script type="text/javascript"></script> <script type="text/javascript" src="<http://pagead2.googlesyndication.com/pagead/show
