The structural connectome and motor recovery after stroke: predicting natural recovery.

Brain : a journal of neurology Aug 17, 2021
Stroke patients vary considerably in terms of outcomes: some patients present 'natural' recovery proportional to their initial impairment (fitters), while others do not (non-fitters). Thus, a key challenge in stroke rehabilitation is to identify indi...

A brain-computer interface that evokes tactile sensations improves robotic arm control.

Science (New York, N.Y.) May 21, 2021
Prosthetic arms controlled by a brain-computer interface can enable people with tetraplegia to perform functional movements. However, vision provides limited feedback because information about grasping objects is best relayed through tactile feedback...

Augmenting intracortical brain-machine interface with neurally driven error detectors.

Journal of neural engineering Dec 1, 2017
OBJECTIVE: Making mistakes is inevitable, but identifying them allows us to correct or adapt our behavior to improve future performance. Current brain-machine interfaces (BMIs) make errors that need to be explicitly corrected by the user, thereby con...

Preservation of hand movement representation in the sensorimotor areas of amputees.

Brain : a journal of neurology Dec 1, 2017
Denervation due to amputation is known to induce cortical reorganization in the sensorimotor cortex. Although there is evidence that reorganization does not lead to a complete loss of the representation of the phantom limb, it is unclear to what exte...

tDCS does not enhance the effects of robot-assisted gait training in patients with subacute stroke.

Restorative neurology and neuroscience Jan 1, 2017
BACKGROUND: Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique, which can modulate cortical excitability and combined with rehabilitation therapies may improve motor recovery after stroke.
