Joint actions require an ability to understand and predict the actions of others far enough into the future to have time to plan and execute matching motor programs. Here I will review experiments in which we have tracked information flow from one brain to another to show that the motor system seems to play a key role in these functions. I will embed this experimental data in a Hebbian learning model, which posits that predictions are the result of synaptic plasticity during self­observation. Jointly this talk will aim to trigger thoughts on how we can study the involvement of the motor system in coordinating actions across individuals
