Fig 3. Steady-state relationship between the dopaminergic input (D) and tapping frequency according to the basal ganglia neurocomputational model.

It is worth-noting that this relationship reaches higher values compared with that used in a previous paper [22] to provide better estimation of patients’ data. This has been achieved by reducing the neuron time constant from 15 to 10 ms, and the time lag between the two movements from 115 to 90 ms.
