Characteristics of 4–6 Hz band, βFB, and non-oscillatory neurons in the Vop/Vim. a Patterns of three neurons with4–6 Hz band, βFB, and non-oscillation. b ISI histograms of three neurons and their MSFR of 23.4 Hz, 33.1 Hz and 19.6 Hz. c Power density spectrum of the three neurons at peak power of 4.5 Hz, 23 Hz, and no power. d Auto-correlation histograms of three patterns of oscillatory neuronal activity; e An example of Vop 4–6 Hz band oscillatory neurons and its coherence with limb tremor; The top trace shows raw data of a 4–6 Hz band oscillatory neuron that corresponds to the limb tremor (FCR); below shows spectral analysis of 4–6 Hz band neuron, limb tremor of FCR, and 4–6 Hz band neuron x FCR, which is the coherence between them. Horizontal line indicates a significant coherent level at 0.42 (p < 0.05). f Comparisons of MSFR, CV and percentages of 4–6 Hz band, βFB oscillatory neurons and non-oscillatory neurons of Vop and Vim. g Histograms demonstrate comparisons of MSFR of total neurons of Vop and Vim
