Disentangling acute motor deficits and adaptive responses evoked by the loss of cerebellar output

This study investigates motor deficits and compensatory responses in monkeys with cerebellar outflow blocked during reaching tasks, finding reduced hand velocity and altered movement strategies.

Cerebellar output shapes cortical preparatory activity during motor adaptation

This study shows that cerebellar signals constrain cortical preparatory activity dimensionality and promote generalization during motor adaptation.

Motor cortical plasticity in response to skill acquisition in adult monkeys

This study shows that motor cortical maps in adult monkeys can symmetrically reorganize in response to training on tasks involving proximal or distal joints, with changes reflecting usage-consistent reorganization rather than local expansion.

Reversible block of cerebellar outflow reveals cortical circuitry for motor coordination

The paper reversibly blocks cerebellar outflow in primates to study its role in motor coordination, finding disruptions in cortical activity timing without affecting spatial tuning or preparatory activity.
