Some pragmatic considerations. Event-related coherence is estimated across trials. In this case gait cycles are the trials and we have at least 220 for each participant. This brings down the noise floor considerably, as it scales with the number of trials: CI = 1 - 0.05^(1/(L-1)). We can therefore detect weak patterns of functional connectivity.

Happy to see our latest paper 'Low-dimensional dynamics of brain-muscle networks during gait' online: https://www.biorxiv.org/content/10.1101/2023.02.02.526912v1

In the paper we distinguish 3 brain-muscle networks that are activated within the gait cycle with different temporal profiles.

This is technically quite interesting as the duration of a gait cycle is only ~1sec, the window length for time-frequency analysis 375 ms, and functional connectivity quite noisy.

Happy to share our latest study with Li-Juan Jie and others investigating the effect of conscious movement processing on postural control and intermuscular coherence
