Is an artificial limb embodied as a hand? Brain decoding in prosthetic limb users.

PLoS Biology, 2020
The potential ability of the human brain to represent an artificial limb as a body part (embodiment) has been inspiring engineers, clinicians, and scientists as a means to optimise human-machine interfaces. Using functional MRI (fMRI), we studied whether

A Phosphenotron Device for Sensoric Spatial Resolution of Phosphenes within the Visual Field Using Non-Invasive Transcranial Alternating Current Stimulation

Sensors
This study presents phosphenotron, a device for enhancing the sensory spatial resolution of phosphenes in the visual field (VF). The phosphenotron employs a non-invasive transcranial alternating current stimulation (NITACS) to modulate brain activity by ...

Vision rehabilitation with the optic nerve visual prosthesis.

, 2004
A blind volunteer with retinitis pigmentosa has been chronically implanted with an optic nerve visual prosthesis. The axons of retinal ganglion cells have been successfully activated by electrical stimuli to evoke many distinct phosphenes over a large ...

Effects of extended stance time on a powered knee prosthesis and gait symmetry on the lateral control of balance during walking in individuals with unilateral amputation

Journal of NeuroEngineering and Rehabilitation, 2019
Background Individuals with lower limb amputation commonly exhibit large gait asymmetries that are associated with secondary health issues. It has been shown that they are capable of attaining improved temporal and propulsive symmetry when walking with a
