A brief summary
Variability in motor control is typically assumed to be due to random noise in the motor system. I challenged this assumption by developing a rigorous investigation into the nature of variability in muscle excitations during cycling. We found fluctuations in muscle excitation (measured with electromyography, or EMG) from cycle to cycle during pedaling are organized in a non-random manner. This organization throughout time is called structure, and it is thought to reveal underlying motor control strategies—for example, we revealed a memory of previous cycles persisting in the EMG signals for several consecutive cycles.
