Examples of STN neuronal phase-locking. A–C: example of a neuron whose firing is phase-locked to parietal cortical oscillations at contralateral movement onset. A: contralateral (red) and ipsilateral (blue) grip force traces. B: β-SPL and γAE-SPL clusters at each timepoint during contralateral grips. C: β-SPL and γAE-SPL clusters at each timepoint during ipsilateral grips. D–F: example of a neuron whose firing is phase-locked to frontal cortical oscillations at ipsilateral movement onset. D: contralateral (red) and ipsilateral (blue) grip force traces. E: β-SPL and γAE-SPL clusters at each timepoint during contralateral grips. F: β-SPL and γAE-SPL clusters at each timepoint during ipsilateral grips. Grip force plots show trial-averaged mean (solid or dashed line) and the extrema (shaded region) of the grip force at each time point. Contra, contralateral; Ipsi, ipsilateral.
