Abstract Parkinson's disease (PD), a neurodegenerative disorder originating in the
dopaminergic cells of the basal ganglia, is characterized by severe motor impairments such …

Previous studies have shown that persons with Parkinson's disease (pwPD) share specific
deficits in learning new sequential movements, but the neural substrates of this impairment …

Sequence learning, a cognitive task linked to cortico-striatal function, is impaired in
Parkinson's disease (PD). We chose this task as a behavioral paradigm to study the …

Early‐stage nondemented Parkinson's disease (PD (es)) patients can learn short but not
long sequences as well as controls. We have previously shown that to achieve normal …

Implicit sequence learning involves learning about dependencies in sequences of events
without intent to learn or awareness of what has been learned. Sequence learning is related …

The capacity to learn new motor sequences is fundamental to adaptive motor behavior. The
early phase of motor sequence learning relies on the ventral and anterior striatal circuitry …

We previously reported a differential effect of dopaminergic medication across the time
course of motor sequence learning in early stage Parkinson's (PD) patients [1]. There was a …

Impairment of sequence learning is common in Parkinson's disease (PD), but the time
course of this cognitive abnormality is not known. We assessed longitudinal changes in …

Parkinson's disease (PD) is characterized by the progressive degeneration of substantia
nigra pars compacta (SNc) dopamine (DA) neurons resulting in striatal DA depletion and …

In this study, the sequence learning performance of 16 non-demented patients with
Parkinson's disease (PD) was compared with 18 age-matched healthy controls on a verbal …
