Neural coding of arm and hand actions is spatially organized in motor cortex

Nicholas G Chehade, Omar A. Gharbawie

The paper shows that neural activity encoding arm and hand movements is spatially organized in motor cortex, with distinct functional selectivity between arm and hand zones during reach-to-grasp tasks.

Neural activity is spatially clustered in motor and dorsal premotor cortex

Nicholas G Chehade, Omar A. Gharbawie

The paper investigates the spatial mapping between motor zones and movement-related neural activity in M1 and PMd cortex, finding that activity maps overlap small portions of motor maps and suggest subzones tuned for specific actions.
