... segments, and to additional dynamic joint interaction forces when the limb moves. We have addressed the question of load compensation in an insect preparation in which a locust makes aimed scratching movements with a hind leg in response to tactile stimulation of a wing. We show that loading the femur...

... after movement was detected, irrespective of the load applied to the abdomen. When the abdomen was physically blocked from extending fully, the sensory neurone did not fire. The tonic muscle receptor organ is considered to be the length-detecting sensor for a load-compensating servo-loop...

... spread of the reflex. The increase in SEMN6 firing rate occurred in the absence of activity in the sensory neurone of the tonic muscle receptor organ, demonstrating that the tonic sensory neurone is not necessary for load compensation during these abdominal extensions in C. destructor . The findings...

.... The results provide the first demonstration that this load-compensating reflex loop operates during naturally evoked extension of the abdomen under constant load. 04 07 1995 © The Company of Biologists Limited 1995 stretch receptor load compensation abdominal posture crayfish Cherax...

... the body forward and counteract the pull of gravity. Thus, it is not surprising that the load on a leg is one factor affecting leg placement and step timing. This influence has been demonstrated in several different insects and crustaceans using Key words: insect locomotion, walking, load compensation, leg...
