This paper explores the idea to create complex human-like movements from movement primitives based on nonlinear attractor dynamics. Each degree-of-freedom of a limb is assumed to have two independent abilities to create movement, one through a discrete dynamic system, and one through a rhythmic system. The discrete system creates point-to-point movements based on internal or external target spe...

previously studies have shown that music can be used to increase the time to engage in physical activity but music's role in controlling the intensity of pa has been studied less. the sensorimotor synchronization (sms), the coordination of rhythmic movement with rhythmic sensory stimuli method, seems to have enough potential and can be applied instead of the previous method for ordinary pe...

Robots execute a wide array of rhythmic behaviors like walking, running, dribbling, etc. Rhythmic movement primitives are parametric models that can be used to represent these behaviors. Previously, these models have been learned either by means of demonstrations or by means of reward signals. While executing a rhythmic behavior, a stabilizing controller is needed in most robots to prevent fail...

The modulation of spinal cord excitability during rhythmic limb movement reflects the neuronal coordination underlying actions of the arms and legs. Integration of network activity in the spinal cord can be assessed by reflex variability between the limbs, an approach so far very little studied. The present work addresses this question by eliciting Hoffmann (H-) reflexes in both limbs to assess...

Microelectrode recordings in the rostral (n. reticularis) and lateral (ventralis lateralis) human thalamus were carried out in locally anaesthetized diskinetic patients during stereotaxic operations. Their responses to voluntary motor tasks prompted by imperative verbal stimuli were tested. Spontaneous and evoked unit activities were studied using computer processing techniques. In the n. retic...

Pectoral fins are known to play important roles in swimming for many adult fish; however, their functions in fish larvae are unclear. We examined routine pectoral fin movement during rhythmic forward swimming and used genetic ablation to test hypotheses of fin function in larval zebrafish. Fins were active throughout bouts of slow swimming. Initiation was characterized by asymmetric fin abducti...
