Fine Temporal Structure of Beta Oscillations Synchronization in Subthalamic Nucleus in Parkinson's Disease
TL;DR: The dominance of short desynchronization events suggests that even though the synchronization in parkinsonian basal ganglia is fragile enough to be frequently destabilized, it has the ability to reestablish itself very quickly.
A closed-loop model of the respiratory system: focus on hypercapnia and active expiration.

TL;DR: This model represents the first attempt to model the transition from quiet breathing to breathing with active expiration and suggests that the closed-loop respiratory control system switches to active expiration via a quantal acceleration of expiratory activity, when increases in breathing rate and phrenic amplitude no longer provide sufficient ventilation.
Transitions between irregular and rhythmic firing patterns in excitatory-inhibitory neuronal networks.
TL;DR: The results suggest that an increase in correlated activity, corresponding to a pathological state, may be due to an increased level of inhibition from the striatum to the inhibitory GPe cells along with an increased ability of the excitatory STN neurons to generate rebound bursts.

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.

Potential mechanisms for imperfect synchronization in parkinsonian basal ganglia.
TL;DR: The changes in firing patterns of STN neuron due to the lack of dopamine may lead to transition from a lower to a higher coherent state, roughly matching the synchrony levels observed in basal ganglia in normal and parkinsonian states.
