Number	Experimental measure	Nucleus	Value	n	Source
7	Oscillation minimum firing rate	STN	0.2 spk/s	1	Bergman et al. (1994)
8	Mean firing rate	STN	25.8 ± 14.9 (SD) spk/s	220	Bergman et al. (1994)
9	Oscillation maximum firing rate	STN	76.9 spk/s	1	Bergman et al. (1994)
10	Oscillation minimum firing rate	GPe	20.7 spk/s	3	Raz et al. (2000)
11	Mean firing rate	GPe	44.8 ± 4.6 (SD) spk/s	445	Raz et al. (2000)
12	Oscillation maximum firing rate	GPe	117.7 spk/s	3	Raz et al. (2000)
13	Oscillation frequency	STN & GPe	15 Hz	220	Bergman et al. (1994); Raz et al. (2000)

The maximum and minimum firing rates of the oscillatory activity for STN and GPe neurons can be extracted from the autocorrelograms used in the cited studies (see supplemental material A, available at www.jneurosci.org). n = number of sample measurements.
