Definition:
"Variations in the behavior by which an organism locates food compared to control animals. In C. elegans roaming or dwelling activity on food are two examples of parameters used to assess this behavior. Roaming is defined as moving in a high-speed forward direction with brief backward movement, often traversing wide regions. Dwelling is defined as low-speed/high turning movement restricted to a confined region." [
