abstract = {Beside locomotion, search movements are another important
type of motor activity of insects. They are very often
performed by the front legs of the animals. They consist of
cyclic stereotypical leg movements that can be modified by
sensory signals. The details of the local organization of
these movements have however not yet been studied. In this
paper, we, using an appropriate variant of our existing
one-leg model, present a scheme of how these searching
movements might be organized and performed on the level of
local neuromuscular control networks. In the simulations
with the model, we attempted to mimic the experimental
results by Berg et al. (J. Exp. Biol. 216:1064–1074, 2013)
in which an obstacle was put in the way of the search
movements of the front leg for a very short while, and then
the recovery to the usual search movements was observed and
analyzed. Our simulation results suggest that the
recruitment of the fast levator and depressor muscles play a
crucial part in resuming the search movements after removal
of the obstacle. The interplay between the levator and
depressor, and the extensor and flexor local control
networks can, according to the model, bring about a large
variety of search movements upon removal of the obstacle. A
number of these movements are comparable with those seen in
the experiments.},
