Journal ArticleDOI
A non-task-oriented approach based on high-dose playful movement exploration for rehabilitation of the upper limb early after stroke: A proposal.
John W. Krakauer,Juan C. Cortes +1 more
TL;DR: A focus on movement quality, rather than task completion, practiced at high intensity and dosage in an enriching environment may be the training approach that best exploits the sensitive period early after stroke in order to amplify the generalized gains seen with spontaneous biological recovery.
Journal ArticleDOI
Hypoperfusion without stroke alters motor activation in the opposite hemisphere
John W. Krakauer,Petya D. Radoeva,Eric Zarahn,Jennifer Wydra,Ronald M. Lazar,Joy Hirsch,Randolph S. Marshall +6 more
TL;DR: It is found that normal performance of two motor tasks was associated with increased ipsilateral hemispheric activation in the patients compared with age‐matched controls and this activation may serve to maintain normal motor performance.

Competition between parallel sensorimotor learning systems
Scott T. Albert,Jihoon Jang,Adrian M. Haith,Gonzalo Lerner,Valeria Della-Maggiore,John W. Krakauer,John W. Krakauer,Reza Shadmehr +7 more
TL;DR: The data show that during sensorimotor adaptation, behavior is shaped by competition between parallel learning systems, such that when the explicit system increases its response, errors are siphoned away from the implicit system, thus reducing its learning.
Journal ArticleDOI
Postural control of arm and fingers through integration of movement commands
Scott T. Albert,Alkis M. Hadjiosif,Jihoon Jang,Andrew J. Zimnik,Demetris S. Soteropoulos,Stuart N. Baker,Mark M. Churchland,John W. Krakauer,Reza Shadmehr +8 more
TL;DR: The data suggest that the postural controller possesses a feedforward module that uses move commands to calculate a component of hold commands, which may arise within an unknown subcortical system that integrates cortical commands to stabilize limb posture.
Journal ArticleDOI
Movement Imitation via an Abstract Trajectory Representation in Dorsal Premotor Cortex.
TL;DR: A novel body-independent route to imitation that relies on the ability to plan abstract movement trajectories within dorsal premotor cortex is proposed, which may also be impaired in some patients with apraxia.
