Bradykinesia is one of the cardinal motor symptoms of Parkinson's disease and other
parkinsonisms. The various clinical aspects related to bradykinesia and the …

Executive dysfunction can be present from the early stages of P arkinson's disease (PD). It is
characterized by deficits in internal control of attention, set shifting, planning, inhibitory …

This paper describes a neural model of speech acquisition and production that accounts for
a wide range of acoustic, kinematic, and neuroimaging data concerning the control of …

Although the basal ganglia play an important role in self‐generated movement, their
involvement in externally paced voluntary movement is less clear. We recorded local field …

Speech production involves the integration of auditory, somatosensory, and motor
information in the brain. This article describes a model of speech motor control in which a …

Patients with Parkinson's disease have great difficulty performing learned movements
automatically. The neural contribution to the problem has not been identified. In the current …

This article describes a computational model, called DIVA, that provides a quantitative
framework for understanding the roles of various brain regions involved in speech …

Event-related functional MRI (fMRI) was used to study blood oxygen level dependent cortical
signal changes associated with volitional limb movements off and on levodopa in …

Humans' ability to synchronize movement with auditory rhythms relies on motor networks,
such as cortical areas, basal ganglia and the cerebellum, which also participate in rhythm …

The neostriatum controls behavioral sequencing, or action syntax, as well as simpler
aspects of movement. Yet the precise nature of the neostriatums role in sequencing remains …
