Steering responses of the model elegans elicited by up-/down-steps. (a), (b) Changes in locomotion track caused by down-steps (a) or up-steps (b). The black curves represent the tracks without stimuli, and the four colored curves respectively represent the tracks after applying an up-/down-step at the four phases of the corresponding colors. (c), (d) Steering response vs. locomotion phase at which a down-step (c) or an up-step (d) was applied. The four colored dotted lines represent the positions of four phases in (a) and (b). The gray dashed lines represent the shape of locomotion in all the phases. The yellow dash-dot lines represent the turning bias when ASEL was not activated or without stimulus. The black dash-dot line in (d) represents the turning bias when ASEL was activated.
