It has been proposed that a form of cortical reorganization (changes in functional connectivity
between brain areas) can be assessed with resting-state (rs) functional MRI (fMRI). Here, …

… The operations were performed for JW and VP in 1979 (ref. 29) and for VJ in 1995. MRI has
confirmed complete resection of callosal fibers for JW 30 and VJ 7 . VP has some remaining …

The cerebellum is an essential part of the neural network involved in adapting goal-directed
arm movements. This adaptation might rely on two distinct signals: a sensory prediction …

Following a stroke, mirror movements are unintended movements that appear in the non-paretic
hand when the paretic hand voluntarily moves. Mirror movements have previously been …

Movements of the upper limb are controlled mostly through the contralateral hemisphere.
Although overall activity changes in the ipsilateral motor cortex have been reported, their …

Impaired hand function after stroke is a major cause of long-term disability. We developed a
novel paradigm that quantifies two critical aspects of hand function, strength, and …

Human motor behavior is constantly adapted through the process of error-based learning.
When the motor system encounters an error, its estimate about the body and environment will …

A common assumption regarding error-based motor learning (motor adaptation) in humans
is that its underlying mechanism is automatic and insensitive to reward- or punishment-…

How is the primary motor cortex (M1) organized to control fine finger movements? We
investigated the population activity in M1 for single finger flexion and extension, using 7T …

Hand and finger movements are mostly controlled through crossed corticospinal projections
from the contralateral hemisphere. During unimanual movements, activity in the …
