Short- and long-term dopamine depletion causes enhanced beta oscillations in the cortico-basal ganglia loop of parkinsonian rats

Enhanced beta power was found in the basal ganglia of both PD models.

An increase in cortical beta power can be only found in the chronic 6-OHDA model.

Beta peak frequencies differ profoundly between the models in the basal ganglia.

Our data support the theory of a relation between beta oscillations and akinesia.

Our study questions the motor cortex as a generator of beta oscillations in PD.
