Grand mean EEG/ECeG and EMG recordings to sternal stimulation during standing with posterior lean and eyes open. A EEG/ECeG evoked responses were less prominent for sternal stimulation compared to C7 and mastoid stimulation, with the most consistent potentials being the P21 and P54 peaks. B Despite sternal stimulation being less effective in evoking EEG/ECeG responses, large and robust EMG responses were recorded from the tibialis anterior (TA) muscles. Baseline rectified EMG levels were 17.0 (soleus) and 73.8 µV (TA)
