There is a clear need to develop non-invasive markers of substantia nigra progression in
Parkinson’s disease. We previously found elevated free-water levels in the substantia nigra for …

Conventional single tensor diffusion analysis models have provided mixed findings in the
substantia nigra of Parkinson’s disease, but recent work using a bi-tensor analysis model has …

Measures from diffusion magnetic resonance imaging reflect changes in the substantia nigra
of Parkinson's disease. It is the case, however, that partial volume effects from free water …

Diffusion tensor imaging could be useful in characterizing movement disorders because it
noninvasively examines multiple brain regions simultaneously. We report a multitarget …

It is well-established that during goal-directed motor tasks, patients with essential tremor have
increased oscillations in the 0–3 and 3–8 Hz bands. It remains unclear if these increased …

A central topic in sensorimotor neuroscience is the static‐dynamic dichotomy that exists
throughout the nervous system. Previous work examining motor unit synchronization reports that …

The basal ganglia‐thalamo‐cortical and cerebello‐thalamo‐cortical circuits are important
for motor control. Whether their functioning is affected in a similar or different way by …

Objective: The objective of this cross-sectional study was to test the hypothesis that patients
with Parkinson disease (PD) and freezing of gait (PD+FOG) would demonstrate sleep …

To investigate whether conscious judgments of movement onset are based solely on pre-movement
signals (ie, premotor or efference copy signals) or whether sensory feedback (ie, …
