Recent electrocorticography data have demonstrated excessive coupling of beta-phase to gamma-amplitude in primary motor cortex and that deep brain stimulation facilitates motor improvement by decreasing baseline phase-amplitude coupling. However, both the dynamic modulation of phase-amplitude coupling during movement and the general cortical neurophysiology of other movement disorders, such as essential tremor, are relatively unexplored. To clarify the relationship of these interactions in…

Cross-frequency phase-amplitude coupling in repetitive movements in patients with Parkinson’s disease

In patients, the modulation of phase-amplitude coupling was similar in (normal executed) pressing, but flattened in slow (abnormally executed) tapping compared to the controls, which may indicate that cross-frequency coupling is involved in the pathophysiology of bradykinesia in Parkinson's disease through its abnormal dynamic modulation.

Synchrony Drives Motor Cortex Beta Bursting, Waveform Dynamics, and Phase-Amplitude Coupling in Parkinson's Disease

These findings reveal a deeper structure to the pathologic changes identified in the neurophysiology of Parkinson's disease, suggesting mechanisms by which the treatment may be enhanced using targeted network synchrony disruption approaches.

Dynamics of human subthalamic neuron phase-locking to motor and sensory cortical oscillations during movement.

The findings provide data that inform models of human basal ganglia function by demonstrating how movement is encoded by networks of subthalamic nucleus (STN) neurons via dynamic phase synchronization with cortex, and demonstrate, for the first time, a mechanism through which the premotor and sensory cortices are functionally connected to the STN.

Altered Pallidocortical Low-Beta Oscillations During Self-Initiated Movements in Parkinson Disease

The results provide a physiological basis for the strategy of using EC movements in PD, circumventing diseased neural circuits associated with SI movements and instead engaging circuits that function similarly to those without PD.

Movement-related changes in pallidocortical synchrony differentiate action execution and observation in humans

A functional dissociation is demonstrated within the BG-cortical network during action execution and observation in which suppression of BG- cortical functional connectivity and local phase amplitude coupling are features specifically of overt movement, suggesting a particularly important role in motor execution.

Magnetoencephalography detects phase-amplitude coupling in Parkinson’s disease

To characterize Parkinson’s disease, abnormal phase-amplitude coupling is assessed in the cortico-basal circuit using invasive recordings. It is unknown whether the same phenomenon might be found in

Movement-Modulation of Local Power and Phase Amplitude Coupling in Bilateral Globus Pallidus Interna in Parkinson Disease

The present results suggest that unilateral motor control involves bilateral basal ganglia networks with movement features differentially encoded by distinct frequency bands, including symmetrical and assymetrical changes between hemispheres.

Cortical phase-amplitude coupling is key to the occurrence and treatment of freezing of gait

It is suggested that elevated phase-amplitude coupling in the primary motor cortex indicates higher probabilities of freezing, and next-generation deep brain stimulation approaches for freezing of gait are developed.

Spatiotemporal features of β-γ phase-amplitude coupling in Parkinson's disease derived from scalp EEG.

Enhanced phase-amplitude coupling of Parkinson's disease patients was enhanced in dorsolateral prefrontal cortex, premotor cortex, primary motor cortex and somatosensory cortex, the difference being statistically significant in the hemisphere contralateral to the clinically more affected side.

Magnetoencephalography-detected Phase-amplitude Coupling in Parkinson Disease

To characterize Parkinson disease, abnormal phase-amplitude coupling is assessed in the cortico-basal circuit using invasive recordings. Whether the same phenomenon might be found in areas other



Oscillations in sensorimotor cortex in movement disorders: an electrocorticography study.

The findings support the emerging hypothesis that disease states reflect abnormalities in synchronized oscillatory activity in basal ganglia-thalamocortical network, and the first study of sensorimotor cortex local field potentials in the three most common movement disorders.

Exaggerated phase–amplitude coupling in the primary motor cortex in Parkinson disease

Analysis of local field potentials recorded from the primary motor cortex (M1) arm area in patients undergoing neurosurgery prompts a model of the basal ganglia–cortical circuit in Parkinson disease incorporating phase–amplitude interactions and abnormal corticosubthalamic feedback.

The cerebral oscillatory network of parkinsonian resting tremor.

Tremor-related oscillatory activity within a cerebral network, with abnormal coupling in a cerebello-diencephalic-cortical loop and cortical motor (M1, SMA/CMA, PM) and sensory (SII, PPC) areas contralateral to the tremor hand is demonstrated.

Synchronized brain network associated with essential tremor as revealed by magnetoencephalography

The results are consistent with the view that in ET, a network of cerebral areas including brainstem shows oscillatory interactions, which lead to a rhythmic modulation of muscle activity becoming apparent as tremor.

Cortical involvement in the generation of essential tremor.

It is hypothesized that tremor oscillations build up in different subcortical and subcortsico-cortico- cortical circuits only temporarily entraining each other.

Human Motor Cortical Activity Is Selectively Phase-Entrained on Underlying Rhythms

It is shown that the activity of neuronal populations is phase-coupled with the beta rhythm on rapid timescales, and how the strength of this relation changes with movement is described.

Movement‐related frequency modulation of beta oscillatory activity in the human subthalamic nucleus

It is shown that frequency modulation of low‐beta and high‐beta rhythms significantly contributes to the involvement of the human STN in movement preparation, execution and recovery, and that the FM patterns are regulated by the dopamine levels in the system.

Regulation of Motor Representation by Phase–Amplitude Coupling in the Sensorimotor Cortex

The results suggest that PAC modulates motor representation in the sensorimotor cortex by holding and releasing high-γ activity in movement-selective cortical regions.
