K_ij and σ_ij are the amplitude and variance of the synaptic weights w_ij, τ₁, and τ₂ are the time constants of STN and GPe respectively (ms), c₁ and c₂ are the axonal propagation velocities from STN and GPe respectively (mm/ms). k_c is the gain of proportional closed-loop stimulation. Protocol A: Sensitivity analysis, Protocol B: Disruption of pathological oscillations, Protocol C: Poor STN photosensitization, Protocol D: Single light source, Protocol E: Effect of acquisition and processing delays.
