A proprioceptive neuromechanical theory of crawling.
The locomotion of many soft-bodied animals is driven by the propagation of rhythmic waves of contraction and extension along the body. These waves are classically attributed to globally synchronized periodic patterns in the nervous system embodied in a central pattern generator (CPG). However, in many primitive organisms such as earthworms and insect larvae, the evidence for a CPG is weak, or e...
متن کاملNeuromechanical models for insect locomotion: Stability, maneuverability, and proprioceptive feedback.
We describe a hierarchy of models for legged locomotion, emphasizing relationships among feedforward (preflexive) stability, maneuverability, and reflexive feedback. We focus on a hexapedal geometry representative of insect locomotion in the ground plane that includes a neural central pattern generator circuit, nonlinear muscles, and a representative proprioceptive sensory pathway. Although the...
متن کاملapplying transitivity theory to gender analysis of efl textbook: : a comparative study.
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
15 صفحه اولA neuromechanical investigation of salamander locomotion
Understanding biological control of locomotion requires not only good models of the neural mechanisms of pattern generation, but also of the interaction of these neural circuits with the body. In this article, we investigate the neural mechanisms underlying the locomotion of the salamander, an animal capable of both aquatic and terrestrial locomotion. A 3D biomechanical simulation of the salama...
متن کاملNeuromechanical Simulation
The importance of the interaction between the body and the brain for the control of behavior has been recognized in recent years with the advent of neuromechanics, a field in which the coupling between neural and biomechanical processes is an explicit focus. A major tool used in neuromechanics is simulation, which connects computational models of neural circuits to models of an animal's body si...
