In the subthalamic nucleus (STN) of Parkinson's disease (PD) patients, a pronounced synchronization of oscillatory activity at beta frequencies (15–30 Hz) accompanies movement difficulties. Abnormal beta oscillations and motor symptoms are concomitantly and acutely suppressed by dopaminergic therapies, suggesting that these inappropriate rhythms might also emerge acutely from disrupted dopamine transmission. The neural basis of these abnormal beta oscillations is unclear, and how they might… Expand

Parkinsonian Beta Oscillations in the External Globus Pallidus and Their Relationship with Subthalamic Nucleus Activity
TLDR
It is proposed that GP neurons, by virtue of their spatiotemporal synchronization, widespread axon collaterals and feed-back/feed-forward mechanisms, are well placed to orchestrate and propagate exaggerated β oscillations throughout the entire basal ganglia in PD. Expand
Beta Frequency Oscillations in the Subthalamic Nucleus Are Not Sufficient for the Development of Symptoms of Parkinsonian Bradykinesia/Akinesia in Rats
TLDR
The results suggest that β frequency oscillations (BFOs) may not be sufficient for the generation of bradykinesia/akinesia in PD, and designed patterns of stimulation that mimicked the temporal characteristics of single unit β bursting activity seen in PD animals and humans are suggested. Expand
Short- and long-term dopamine depletion causes enhanced beta oscillations in the cortico-basal ganglia loop of parkinsonian rats
TLDR
The reserpine model is investigated, which is characterized by an acute and stable disruption of dopamine transmission, and compared it to the chronic progressive 6-hydroxydopamine (6-OHDA) model, which further support the hypothesis of an important pathophysiological relation between enhanced beta activity and akinesia in parkinsonism. Expand
Subthalamic beta oscillations correlate with dopaminergic degeneration in experimental parkinsonism
TLDR
This study is the first to show a strong relation between subthalamic beta power and the dopaminergic neurodegeneration, and provides additional evidence for an important pathophysiological role of subthalamus beta oscillations and prolonged beta bursts in Parkinson's disease. Expand
Subthalamic Nucleus Neurons Are Synchronized to Primary Motor Cortex Local Field Potentials in Parkinson's Disease
TLDR
In humans undergoing deep brain stimulator implantation surgery, the novel technique of subdural electrocorticography in combination with subthalamic nucleus (STN) single-unit recording is used to study basal ganglia–cortex interactions at the millisecond time scale to support a model of the basalganglia-thalamocortical loop in PD. Expand
Mechanistic insights into neuronal oscillatory activity in the dopamine-intact and dopamine-depleted primary motor cortex
In Parkinson’s disease (PD) the loss of the neurotransmitter dopamine (DA) results in abnormal oscillations of the cortico-basal ganglia network, the emergence of which correlate with symptoms.Expand
Striatal cholinergic interneurons generate beta and gamma oscillations in the corticostriatal circuit and produce motor deficits
TLDR
It is demonstrated that a single cell type, the striatal cholinergic interneuron, mediates the emergence of exaggerated beta oscillations within CBT circuits of normal mice and induces parkinsonian-like motor deficits in otherwise normal mice. Expand
Brain state-dependent alterations of corticostriatal synchronized oscillations in awake and anesthetized parkinsonian rats
TLDR
Data support that synchronized high beta oscillations are directly related to the motor symptoms of PD and anesthesia regimes influence the excessive synchronized oscillations between the cortex and striatum in a brain state-dependent manner. Expand
Phase-Dependent Suppression of Beta Oscillations in Parkinson's Disease Patients
TLDR
It is demonstrated that STN beta oscillations can be suppressed when consecutive electrical pulses arrive at a specific phase of the oscillation, which could provide a valuable neuromodulation strategy for the treatment of brain disorders and for elucidating the role of neuronal oscillations in the healthy brain. Expand
Alterations in Brain Connectivity Underlying Beta Oscillations in Parkinsonism
TLDR
A novel perspective is provided on how altered connectivity in basal ganglia-thalamocortical circuits reflects a balance between pathogenesis and compensation, and predicts potential new therapeutic targets to overcome dysfunctional oscillations. Expand

Dopamine depletion increases the power and coherence of β‐oscillations in the cerebral cortex and subthalamic nucleus of the awake rat
TLDR
A crucial role for dopamine is supported in the modulation of population activity in cortico‐basal ganglia circuits, whereby dopaminergic mechanisms effectively filter out synchronized, rhythmic activity at β‐frequencies at the systems level, and shift temporal couplings in these circuits to higher frequencies. Expand
Synchronous oscillations and phase reorganization in the basal ganglia during akinesia induced by high‐dose haloperidol
TLDR
It is demonstrated that acute DA blockade is sufficient to produce synchronous oscillatory activity across basal ganglia neuron populations, and that prolonged DA blockade results in phase lag changes in pallidostriatal synchrony. Expand
Dopamine Dependency of Oscillations between Subthalamic Nucleus and Pallidum in Parkinson's Disease
TLDR
Local potentials from the globus pallidus interna and subthalamic nucleus are recorded in four awake patients after neurosurgery for Parkinson's disease to demonstrate synchronization of activity does occur between pallidum and STN, and its pattern is critically dependent on the level of dopaminergic activity. Expand
Dopamine-dependent changes in the functional connectivity between basal ganglia and cerebral cortex in humans.
TLDR
The basal ganglia may receive multiple cortical inputs at frequencies <30 Hz and, in the presence of dopaminergic activity, produce a high frequency drive back to the cerebral cortex, in particular the supplementary motor area (SMA). Expand
Levodopa‐induced modulation of subthalamic beta oscillations during self‐paced movements in patients with Parkinson's disease
TLDR
The findings suggest that the beta ERD recorded in the STN area reflects motor‐preparative processes that are at least partly dependent on dopaminergic activity within the basal ganglia. Expand
Beta oscillatory activity in the subthalamic nucleus and its relation to dopaminergic response in Parkinson's disease.
TLDR
The findings suggest that the degree of neuronal beta oscillatory activity is related to the magnitude of the response of the basal ganglia to dopaminergic agents rather than directly to the motor symptoms of PD. Expand
Oscillations in the basal ganglia under normal conditions and in movement disorders
TLDR
The most significant finding is that in Parkinson's disease synchronized oscillatory activity in the 10‐ to 35‐Hz band (often termed “β‐band”) is prevalent in the basal ganglia–thalamocortical circuits, and that such activity can be reduced by dopaminergic treatments. Expand
Visually Guided Movements Suppress Subthalamic Oscillations in Parkinson's Disease Patients
TLDR
It is suggested that visually guided movements are associated with a dampening and desynchronization of oscillatory activity in STN neurons, hence facilitating movement. Expand
Dopamine regulates the impact of the cerebral cortex on the subthalamic nucleus–globus pallidus network
TLDR
These data suggest that abnormal low-frequency oscillatory activity in the subthalamic nucleus-globus pallidus network in the dopamine-depleted state is generated by the inappropriate processing of rhythmic cortical input. Expand
Dependence of subthalamic nucleus oscillations on movement and dopamine in Parkinson's disease.
TLDR
It is suggested that the firing of STN neurones can be synchronized by 15-30 Hz cortical beta oscillatory activity, particularly when dopamine deficiency results in a higher background firing rate of STn neurones, and that this synchronization contributes to parkinsonian pathophysiology. Expand
