Data for: Hybrid dedicated and distributed coding in PMd/M1 provides separation and interaction of bilateral arm signalsTanner Dixon, Christina Merrick, Joni Wallis, Richard Ivry & Jose Carmena
Pronounced activity is observed in both hemispheres of the motor cortex during preparation and execution of unimanual movements. The organizational principles of bi-hemispheric signals and the functions they serve throughout motor planning remain unclear. Using an instructed-delay reaching task in monkeys, we identified two components in population responses spanning PMd and M1. A “dedicated” component, which segregated activity at the level of individual units, emerged in PMd during preparation. It was most prominent following movement...
