Natural behavior requires flexible adjustments, for example when navigating complex environments or escaping predators. Previously, whole-brain recordings in C. elegans uncovered that a large proportion of neuronal activity relates to motor commands. However, the role of these distributed motor commands remains elusive.Here, we investigate changes in a C. elegans motor behavior and the corresponding distributed dynamics upon an environmental change. We find that environments that make movement more difficult provoke longer backwards movement, so-called “reversals”. Importantly, this prolongati
