Detecting the temporal structure of intermittent phase locking
TL;DR: It is shown that the obtained measures can describe the differences in the dynamics and temporal structure of synchronization and desynchronization events for the systems with a similar overall level of phase locking and similar stability of the synchronized state.

Short desynchronization episodes prevail in synchronous dynamics of human brain rhythms
Sungwoo Ahn,Leonid L. Rubchinsky +1 more
TL;DR: The observed prevalence of short (but potentially frequent) desynchronization events (length of one cycle of oscillations) may have important functional implications for the brain.
Interaction of synchronized dynamics in cortex and basal ganglia in Parkinson's disease.
Sungwoo Ahn,S. Elizabeth Zauber,Robert M. Worth,Robert M. Worth,Thomas C. Witt,Leonid L. Rubchinsky,Leonid L. Rubchinsky +6 more
TL;DR: The observations suggest that there may be multiple functional modes by which the cortical and basal ganglia circuits interact with each other in Parkinson's disease: not only may synchronization be observed between some areas in cortex and the basal Ganglia, but also synchronization within cortex and within basalganglia may be related, suggesting potentially a more global functional interaction.

Short desynchronization episodes prevail in synchronous dynamics of human brain rhythms
Sungwoo Ahn,Leonid L. Rubchinsky +1 more
TL;DR: In this article, the temporal structure of phase-locking was analyzed to study the temporal patterning of synchrony of the human brain rhythms, and it was shown that the probability for a desynchronization episode to occur decreased with its duration.

Synchronized Beta-Band Oscillations in a Model of the Globus Pallidus-Subthalamic Nucleus Network under External Input.
Sungwoo Ahn,S. Elizabeth Zauber,Robert M. Worth,Robert M. Worth,Leonid L. Rubchinsky,Leonid L. Rubchinsky +5 more
TL;DR: In this article, the subthalamo-pallidal model network exhibits multiple resonances in response to inputs in the beta frequency band, representing cortical input, which may indicate that these basal ganglia circuits are directly involved in the expression of Parkinsonian synchronized beta oscillations.
