Corticothalamic feedback and sensory processing
Current Opinion in Neurobiology, 2003Although nearly half of the synaptic input to neurons in the dorsal thalamus comes from the cerebral cortex, the role of corticothalamic projections in sensory processing remains elusive. Although sensory afferents certainly establish the basic receptive field properties of thalamic neurons, increasing evidence indicates that feedback from the cortex ...

Sensory feedback in upper limb prosthetics
Expert Review of Medical Devices, 2013One of the challenges facing prosthetic designers and engineers is to restore the missing sensory function inherit to hand amputation. Several different techniques can be employed to provide amputees with sensory feedback: sensory substitution methods where the recorded stimulus is not only transferred to the amputee, but also translated to a different

Sensory feedback control for space manipulators
Proceedings, 1989 International Conference on Robotics and Automation, 1993The positioning control problem of the end tips of space manipulators which have no fixed bases is investigated. According to the momentum-conservation law, the system is represented by a nonholonomic model. Thus, the conventional control method for industrial robots, based on a local feedback at each joint, is not applicable when the end tip must be ...

Sensory Dead Zones: Switching Feedback
2021An expert pole balancer cannot balance a 0.3 m stick at their fingertip for longer than 5 s if one eye is patched! This is a consequence of the limited ability of human depth perception in the sagittal (anterior-posterior) plane.

Restorative Neurology and Neuroscience, 2015
Purpose: Musician’s dystonia (MD) is a task-specific movement disorder related to extensive expert music performance training. Similar to other forms of focal dystonia, MD involves sensory deficits and abnormal patterns of sensorimotor integration. The present study investigated the impaired cortical sensorimotor network of pianists who suffer from MD ...

Sensory Feedback And Compliance
1984A common problem in robotics is to bring a tool to a certain spatial relationship to a workpiece, or to bring two or more components together into a certain spatial relationship. However, owing to accumulation of dimensional variation and tolerances that cannot be minimised at their source, errors can occur, making it unexpectedly difficult or ...

Sensory feedback for upper limb prostheses
2011In this chapter, we discuss the neurophysiological basis of how to provide sensory feedback to users with an upper limb prosthesis and discuss some of the theoretical issues that need to be considered when directly stimulating neurons in the somatosensory system. We focus on technologies that are currently available and discuss approaches that are most

Sensory feedback for powered limb prostheses
Medical & Biological Engineering, 1975The results of these tests confirm that a prosthesis is easier to control with sensory feedback and that the proposed technique is acceptable to patients as well as to professionals working in this field. Work in this Institute is now directed toward development of the feedback system to a form suitable for inclusion in a prosthesis.

Sensory-feedback system compatible with myoelectric control
Medical & Biological Engineering & Computing, 1980Progress in the development of a system to provide sensory feedback of the pinch force of an artificial hand is described. Design criteria relating to electrocutaneous stimulation and compatibility with myoelectric control are discussed. Details of a practical system, presently in use by two amputees prior to full-scale clinical evaluation, are ...

Sensory Feedback in locomotion control
2008This chapter focuses on the sensing processes and their interactions with locomotion control. The analysis has been accomplished taking into account different levels of behavior. Moreover dynamic simulators and robotic structures have been used to investigate the biological principles governing the sensory feedback in the real world.
