Table 4. DBS-induced FTG in humans.

Studies presented in chronological order. In both studies, DBS induces FTG off dopaminergic medication and without dyskinesias. M1: primary motor cortex; SMA: supplementary motor area; PMC: premotor cortex; STN: subthalamic nucleus; PD: Parkinson’s disease, OFF: off dopaminergic medication; FFT: fast fourier spectrum

Study Location Disorder Medication Methods Main Findings
Wiest et al., 2021 STN PD OFF short-time FFT (1 s Hamming window,25% overlap, 1 Hz resolution) DBS induces FTG during and/or after stimulation without detectable dyskinesias, FTG is not entrained at half stimulation frequency
Muthuraman et al.,2020 M1, SMA, PMC, STN, cerebellum PD OFF multitaper method(seven orthogonal tapers were used) cross-frequency coupling of FTG power to the power of clinically effective DBS frequency
