Swimming Frequencies of Freely Swimming C. elegans

Most, if not all, studies of thrashing frequencies of swimming frequencies of C. elegans have been conducted using microscopic techniques.   Microscopic techniques require microscopic life to remain in a focal plane within microns.  Using microscopic techniques, the C. elegans are therefore ‘slipping and sliding’ on a microscope slide in a water droplet.  The worms are then not truly freely swimming since they are making contact with the microscope slide.  Using laser diffraction, we found that the average thrashing frequency of swimming C. elegans differs significantly from nematodes on a microscope slide by about 0.3 Hz.  Our new article on thrashing thrashing frequencies of freely swimming C. elegans can be downloaded from the Open Journal of Biophysicshttp://www.scirp.org/journal/PaperInformation.aspx?paperID=21423

Opto-Mechanical Shape Analysis

This publication was born out of Prof. Magnes’ opto-mechanical integration work (also published in the Journal of Applied Optics). This opto-mechanical scanning method can be a stand-alone shape recognition technique requiring minimal computational power. We can also invision this technique as a complimentary method to existing shape recognition technique taking advantage of an symmetry evaluation.
