Video 1: Real-time crawling locomotion in structured microfluidic arenas.
Video 2: Loading of animals into a two-arena device and introduction of an odor stripe across both arenas. Sensory mutant tax-4 (left) does not respond to the odor, whereas wild-type (right) animals are attracted to the odor stripe.
Video 3: Pulses of odor (~1 uM isoamyl alcohol) elicit turns (red) and reversals (black) upon odor removal. Image processing algorithms identify each animal, automatically determine its behavior, and assemble behavioral ethograms (right) indicating responses to the odor pattern (top).
Video 4: Wild-type animals navigate within two attractive odor stripes containing ~1 uM isoamyl alcohol.
