Figure 1
The microfabricated platform with the linear array of asymmetric funnel barriers in the middle used to study the rectification behavior of C. elegans wild-type N2.
(A) Schematic drawing of the putative mechanosensory neurons on the anterior end and body (based on articles in the Wormbook25,26). (B) Schematic drawing of the experimental setup. C. elegans on an agar plate underwent rectification and became concentrated on the right side (labeled R) over time. (C) Schematic drawing of the control setup where the barriers are symmetric. In this case, there is no rectification and C. elegans were equally distributed between the left (L) and right (R) sides.
