WebC. elegans thermotaxis is particularly interesting as it reveals an interplay of multiple neural functions [1]. Worms adjust a stored set-point of thermotactic memory to their cultivation temperature (T cult). When navigating thermal gradients at temperatures above the thermotactic set-point (T > T cult), C. elegans crawls down thermal gradi- WebFeb 4, 2024 · Paraquat-induced oxidative stress reduces the electrotaxis speed of C. elegans. Oxidative stress is known to affect the behavioral responses of C. elegans … WebLuo et al. 2010). Thus, as in negative thermotaxis in C. elegans, the larva is capable of biasing a random walk toward preferred temperatures. Unlike negative thermotaxis in C. elegans, the angular changes evoked by reorientation maneuvers in spatial temperature gradients tend to be toward the preferred temperature in Drosophila larvae (Fig. 1D,G). cabinet makers limerick
