late paralysis arrested elongation two fold
In C. elegans, movement and elongation stop nearly simultaneously soon after the twofold stage of elongation. However, mutant embryos twitch at the one-and-a-half-fold stage of elongation, like control animals, and move as well as control animals at the two- fold stage.
light touch habituation variant
Any variation in the decreased behavioral response to repeated light head or tail touch compared to control. A gentle touch to the animal's head causes backward movement, whereas a gentle touch to the animal's tail causes forward movement. When wild-type animals are touched repeatedly on the head or tail, after some repetition they stop responding to the touch stimulus.
