FIGURE 3.
Effect of open-loop DBS parameters on STN LFP beta-band power. (A) The STN LFP beta-band power was calculated during DBS with fixed 60 μs pulse duration and varying stimulation amplitude and frequency. The LFP beta-band power was normalized against the LFP beta-band power recorded when was DBS off. Stimulation amplitude and frequency values of 0 corresponded to the condition where DBS is off, resulting in an LFP beta-band power value of 1. (B–E) Examples of the STN LFP for varying stimulation amplitude and frequency values.
