Pattern generation for stick insect walking movements—multisensory control of a locomotor program
TLDR
Decisions in modular systems and Generation of reflex reversal by a distributed network are discussed. Expand
The femur-tibia control system of stick insects — a model system for the study of the neural basis of joint control

  • Brain Research Reviews
  • 1 May 1993
TLDR
The femur-tibia control system of stick insects is investigated and it is discussed that most of the characteristics of this system are, at least qualitatively, similar to joint control systems in other animals. Expand
Functional principles of pattern generation for walking movements of stick insect forelegs: the role of the femoral chordotonal organ afferences
TLDR
Electrical stimulation of the nerve containing the axons of trochanteral campaniform sensilla and of the hairfield trHP decreased the likelihood that concurrent chordotonal organ stimulation would elicit an active reaction, indicating that the walking pattern generator is composed of subunits that are only loosely coupled centrally; it probably does not include a central pattern generator; and generation of an active response is a two-step process.

Physiology of the Femoral Chordotonal Organ in the Stick Insect, Cuniculina Impigra
TLDR
The femoral chordotonal organ of the stick insect Cuniculina impigra Redtenbacher (Phasmida) can be stimulated precisely by moving the receptor apodeme, thus providing further evidence of rangefractionation. Expand
Sense organs in the femur of the stick insect and their relevance to the control of position of the femur-tibia-joint

  • Journal of comparative physiology
  • 2004
TLDR
Two receptors at the dorsal side of the femur-tibia-joint, which are situated in the same position as in Schistocerca hind legs, react phasically to extension movements and fire tonically in the most extended position of the joint. Expand
The walking-(and searching-) pattern generator of stick insects, a modular system composed of reflex chains and endogenous oscillators
  • U. Bässler
  • Computer Science
  • Biological Cybernetics
  • 1 August 1993
TLDR
It is demonstrated that the walking- and searching-pattern generators cannot be separated, at least not for the movements investigated and some of them additionally seem to depend on the context signalled by other sense organs. Expand
Motor Output of the Denervated Thoracic Ventral Nerve Cord in the Stick Insect Carausius Morosus
The denervated thoracic ventral nerve cord produces a motor output which is similar to that observed in the intact animal during irregular leg movements (seeking movements) or rocking, but notExpand
Reversal of a reflex to a single motoneuron in the stick insect Çarausius morosus
  • U. Bässler
  • Mathematics
  • Biological Cybernetics
  • 1 March 1976
In “inactive” stick insects ramp-wise stretching of the femoral chordotonal organ excites the slow extensor tibiae motoneuron. In “active” animals the same stimulus decreases the firing rate of thisExpand
The role of sensory signals from the insect coxa-trochanteral joint in controlling motor activity of the femur-tibia joint.
TLDR
Experiments showed that fCS activity plays an important role in generating tibial motoneuron activity during the stance phase of walking, and suggested that sensory signals from the CT joint only weakly affect central rhythm-generating networks of the FT joint. Expand
On the definition of central pattern generator and its sensory control
A central pattern generator (CPG) is defined here as a neural network responsible for the production of the timing cues of a rhythmic motor output pattern in the isolated CNS. For the intact animal,Expand
