Effects of T-type and L-type calcium currents on synchronized activity patterns in a model subthalamo-pallidal network
Choongseok Park, Leonid L. Rubchinsky, Sungwoo Ahn
Synchronized rhythmic oscillatory activity in the beta frequency band in the basal ganglia (BG) is a hallmark of Parkinson's disease (PD). Recent experiments and theoretical studie…
Mathematical model of subthalamic nucleus neuron: characteristic activity patterns and bifurcation analysis
Choongseok Park, Leonid L. Rubchinsky, Sungwoo Ahn
The subthalamic nucleus (STN) has an important role in the pathophysiology of the basal ganglia in Parkinson's disease. The ability of STN cells to generate bursting rhythms under…
Dynamics of desynchronized episodes in intermittent synchronization
Leonid L Rubchinsky, Sungwoo Ahn, Choongseok Park
Intermittent synchronization is observed in a variety of different experimental settings in physics and beyond and is an established research topic in nonlinear dynamics. When coup…
Failure of Delayed Feedback Deep Brain Stimulation for Intermittent Pathological Synchronization in Parkinson's Disease
Andrey Dovzhenok, Choongseok Park, Robert M. Worth +1
Suppression of excessively synchronous beta-band oscillatory activity in the brain is believed to suppress hypokinetic motor symptoms of Parkinson's disease. Recently, a lot of int…
Potential mechanisms for imperfect synchronization in parkinsonian basal ganglia
Choongseok Park, Leonid Rubchinsky
Neural activity in the brain of parkinsonian patients is characterized by the intermittently synchronized oscillatory dynamics. This imperfect synchronization, observed in the beta…
Intermittent synchronization in a network of bursting neurons
Choongseok Park, Leonid L. Rubchinsky
Synchronized oscillations in networks of inhibitory and excitatory coupled bursting neurons are common in a variety of neural systems from central pattern generators to human brain…
