An example of an RMS-smoothed multi-unit (MU) burst (C) recorded recorded from the cat MCx and simultaneously recorded EMG activity (A,B) of the two muscles in which activity was evoked. (D) The cross-correlation function between the MCx waveform and the respective EMG waveforms. Bursting spike activity in the MCx was produced by focal iontophoretic ejection at a cortical point of the GABA_A receptor antagonist Bicuculline (see Capaday et al., 2011). The EMG recording where low-pass filtered at 100 Hz, whilst the MCx spiking activity was filtered at 1 KHz. The waveforms are averages of eight consecutive responses.
