Duration-modulated neural population dynamics in humans during BMI controls (opens in new tab)

The motor cortex (MC) is often described as an autonomous dynamical system during movement execution. In an autonomous dynamical system, flexible movement generation depends on reconfiguring the initial conditions, which then unwind along known dynamics. An open question is whether these dynamics govern MC activity during brain-machine interface (BMI) control. We investigate MC activity during BMI cursor movements of multiple durations, ranging from hundreds of milliseconds to sustained over ...
