Tremor onset-related cortical potential in α1
mice. (A) Schematic diagram of EEG, EMG, and accelerometer recordings during mouse behavior. EMG activity was recorded from triceps brachii of left and right forelimbs. Topography of the high-resolution EEG array attached to the skull (middle) and locations of channels (right). The topography of the high-resolution EEG array was adapted with permission from Lee et al. (2011) . (B) Representative EEG, EMG, and accelerometer (Acc.) traces upon α1-/-;α1G−/− tremor onset. The EMG shown is from the right forelimb. (C) ERPs of tremor onset. Different colored traces indicate averaged activity of different channels. (D) Spectrogram (top), inter-trial coherence (bottom), and (E) 15–30 Hz power of ERPs from the left S1 (n = 3) during tremor onset. Ol, olfactory cortex; FrA, frontal association cortex; M2, secondary motor cortex; M1, primary motor cortex; S1, primary somatosensory cortex; V2, secondary visual cortex; V1, primary visual cortex; Cb, cerebellar cortex.
