DBS Desynchronization 2D: Basal Ganglia Phase-Circle

In Parkinson's disease, neurons in the subthalamic nucleus fall into excessive beta-band (13–30 Hz) synchrony, and that pathological synchrony is thought to underlie bradykinesia and rigidity. This 2D companion renders 180 STN neurons as coupled phase oscillators (a Kuramoto model) on two linked panels — a real anatomical cross-section showing the DBS electrode's volume of tissue activated, and a phase-circle plot of the population's order parameter r·e^(iψ) — tracked live as the recurrent coupling strength K, and a real deep brain stimulation pulse train's frequency, amplitude and reach, are tuned in real time. Both panels are computed directly in the plane from the same governing equations as the 3D version, letting you see the spatial reach of the electrode and the degree of phase-locking side by side.
