Healthy behaviour: adequate response to external stimulus with a high enough dopamine level to make the BG direct pathway dominant. Spectrogram and power histogram analysis results of dominant frequencies for the firing activity of the D2-MSNs, the GPe, the D1-MSNs and the STN. The dominant frequencies of the STN-GPe network are at gamma-frequency band (30–150 Hz) and the network synchronisation is low
