Animal experiments suggest that 2 different types of activated microglia (AMG) cells occur in
the brain after a stroke: local AMG in the area of the infarct and remote AMG, which occurs …

Rigidity or hypertonicity is a cardinal symptom of Parkinson's disease (PD). We hypothesized
that hypertonicity of the body axis affects functional performance of tasks involving balance, …

When walking on a split-belt treadmill, where each leg is driven at a different speed, a temporary
change is made to the typical steady-state walking pattern. The exact ways in which the …

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique
that induces changes in cortical excitability: anodal stimulation increases while cathodal …

The head, containing the gravity sensors (vestibular system) and the visual system, must be
stabilized in space to provide a steady reference. During walking, the head also needs to be …

Neuroimaging-derived markers are used to model post-stroke impairment. Among these,
lesion size, corticospinal-tract lesion-load (CST-LL) and resting-state functional-connectivity (rs-…

Visual tracking of the surrounding environment is an important daily task, often executed
simultaneously with the regulation of upright balance. Visual and postural coordination may be …

Background In healthy subjects, the act of walking and turning is accomplished by a sequential
horizontal reorientation of gaze, head, and body toward the direction of the turn. Subjects …

Many studies of split-belt treadmill adaptation have been focused on the biomechanical
changes that occur in response to walking on belts at different speeds. This process of …

Freezing of gait (FOG) is a common motor symptom in Parkinson's disease (PD) thought to
arise from the dysfunctional cortico-basal ganglia-thalamic circuity. The purpose of this study …
