Table 2.

Model details.

Models 1–3 use activity change in the beta band (β) and gamma bands (γ) from the STN LFP as model inputs. Models 4 and 5 take into account extra information about the low frequency activity change (α). Models 6–8 only use the activity change from a single frequency band (α, β and γ, respectively) as model input. T_p and T_d are the time constant and time delay of the first order linear dynamic model, respectively.
