Uncertainty differentially shapes premotor and primary motor activity during movement planning

Precise movement execution often relies on adequately planning the upcoming action, a process that is largely mediated by the dorsal premotor (PMd) and primary motor (M1) cortices. Due to their anatomical and functional similarities, PMd and M1 are commonly assumed to contain similar planning- related information. Here we show that when planning movements under uncertainty, the activity of PMd and M1 neural populations show distinct features, suggestive of area-specific computations. We analyzed simultaneous recordings from populations of PMd and M1 neurons from monkeys performing both a stand
