... walking leg coordination kinematics stick insect Walking in all kinds of organisms shows a high degree of variability in the stepping kinematics despite its often stereotypical appearance. This form of locomotion assures survival through great adaptability and the possibility of coping...

... morosus ) adapts in parallel to strong context-dependent adaptation of step kinematics and inter-leg coordination. The behavioural contexts we chose were straight walking and visually induced curve walking, for both of which the steady state limb kinematics and inter-leg coupling strengths were known...

... speeds, for outer leg 2. As coordinating influences between contra-and ipsilateral legs were found directly to influence only the anterior extreme position of the legs, these results indicate that the mechanisms controlling curve walking may be different from those controlling normal leg coordination...

... in a specific manner to locomotion. Second, ipsi-and contralateral leg coordination was investigated. Ipsilateral coordination was found to involve a metachronal organization from front to back in all the walking sequences recorded, whereas contralateral coordination involved, in addition to the weak alternate...

... adult female stick insects, Carausius morosus Br., walking on a treadwheel. The insects were taken from laboratory colonies in Bielefeld. Leg coordination was recorded using previously described methods (Dean, 1984). A holder was attached dorsally to the insect along the tergum of the head, thorax...

... influences which have been found to exist between ipsilateral legs. However, in contrast to ipsilateral legs, the interaction between two contralateral legs was found to act in both directions. 08 02 1989 © 1989 by Company of Biologists 1989 walking leg coordination insects Carausius...

..., the influence being stronger the further the anterior leg has moved backwards during its retraction. The latter influence depends on the position but not the phase of the anterior leg. 10 5 1988 © 1988 The Company of Biologists Ltd. 1988 walking leg coordination insects Carausius...

...Jeffrey Dean; Gernot Wendler ABSTRACT Continuous measurements of anterior-posterior leg position recorded from stick insects walking on a wheel were tested for relationships among spatial and temporal parameters of leg coordination. This analysis revealed that the protraction of middle and rear...
