(A) Pre-surgery axial (left) and coronal (right) MRI and (B) post-surgery coronal (left) and axial (right) MRI showing the apical temporal lobe resection and the shrinkage of the hippocampal remnant. L = Left hemisphere; R = Right hemisphere.

Amygdala, and the post-surgery MRI revealed a shrinkage of the left hippocampal remnant (Figures 1A,B).
(A) Fourier Transform (FFT) of the Electromyogram (EMG)-activity of the wrist flexor and extensor and the coactivation of the right arm. A peak-frequency of about 7 Hz is visible. (B) Coherence between EMG-activity for the wrist flexor and extensor and the accelerometer-signal (upper two rows), and coherence between the coactivation and the accelerometer signal (third row). Coherence is highest at the same frequency of about 7 Hz found with the FFT. AU = arbitrary units; FFT = Fourier transform; EMG = Electromyogram.

The results revealed a tremor-related signal with a mean-frequency of 7.5 Hz (Figure 2A) and a coactivation of the wrist flexor and extensor muscles at the same frequency of 7.5 z. Coherence analysis revealed a coherence between EMG-activity and the tremor at 7.5 Hz for each muscle as well as a coherence between the accelerometer and the coactivation of both muscles (Figure 2B).
