... legs. In insects, slope-dependent adjustments have mainly been examined under steady-state conditions, whereas the transition dynamics have been largely neglected. In a previous study, we showed that steady-state adjustments of stick insects to ±45 deg slopes involve substantial changes in joint...

... efficiency of finding foothold by avoiding searching-movements in trailing legs. In stick insects, a ‘targeting mechanism’ has been described that guides foot-placement of hind- and middle legs according to the position of their leading ipsilateral leg. So far, this mechanism has been shown for standing...

...Martyna Grabowska; Elzbieta Godlewska; Joachim Schmidt; Silvia Daun-Gruhn SUMMARY The analysis of inter-leg coordination in insect walking is generally a study of six-legged locomotion. For decades, the stick insect Carausius morosus has been instrumental for unravelling the rules and mechanisms...

...Matthias Gruhn; Lyuba Zehl; Ansgar Büschges SUMMARY In stick insects, walking is the result of the co-action of different pattern generators for the single legs and coordinating inter-leg influences. We have used a slippery surface setup to understand the role the local neuronal processing...

...Malcolm Burrows SUMMARY The stick insect Timema chumash belongs to a sub-order of the phasmids that is thought to have diverged early from other stick insects, and which is restricted to the southwest of North America. It jumps by rapidly extending the tibiae of both its hind legs simultaneously...

... as changes in coordination between legs. Moreover, the unpredictable variety of real life situations implies that compensatory responses should be sensitive to the behavioural context of the animal. We have investigated the extent to which the compensatory response of a walking stick insect ( Carausius...

... a behavioural transition do so at the same rate. The present study tests this assumption by analysing the sequence of kinematic events during turning of the stick insect Carausius morosus , and by measuring how the time courses of the changing parameters differ between legs. Turning was triggered reliably...

Generally coupling strength of the underlying mechanisms has been considered constant rather than context-dependent. The present study analyses stepping patterns of the stick insect Carausius morosus during...

It enables the joint control loop to work with a high gain but it prevents instability oscillations. In the inactive stick insect, the realisation of specific...

The insect walked on a lightweight double treadwheel under open-loop or closed-loop conditions. The open-loop...
