Tremor onset-related cortical potential in α1 −/− ;α1G −/− 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) [18]. (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.
