When running the function 'coherenceAnalysis_Borzelli_et_al_JNeurophysiol_2024.m', the code load the firings of the motor units identified during two exemplificative trials performed by a participant, saved in 'data_Borzelli_et_al_JNeurophysiol_2024'. One trial was directed toward an horizontal target of the perturbed block and the other was directed toward a supination target of the baseline block.

Then the code calculates the coherence between the MUs identified on the BB and on the TB (cross-muscle coherence) and the cross-muscle coherence after excluding the components synchronized with the norm of the endpoint force.

Finally, the code plots the results.

This code could easily be modified to compute all the relevant analyses presented in the paper, such as the total within muscle coherence and the within muscle coherences after excluding the components synchronized with the norm of the force or the sum of the firings of the antagonist muscle.
