Biological- or artificial-arm experience during early development has a significant effect on artificial-arm motor control in adulthood, providing evidence for limited sensorimotor plasticity beyond childhood.
During a sensorimotor perturbation, task outcome may serve as a gain on implicit adaptation or provide a distinct error signal for a second, independent implicit learning process.

An electrode-wise encoding model based on physiological recordings from the cortical surface revealed a striking hemispheric asymmetry where the encoding of ipsilateral movement was stronger in the left hemisphere compared to the right hemisphere.
Theoretical models and experimental results reveal how the optimal integration of gravity cues fine tunes movement kinematics so that motor effort is minimized in the ubiquitous gravity field.

A new collection of fly strains comprehensively targets the motor neurons of the proboscis, allowing separate control of every muscle to determine how this appendage achieves flexible, directed reaching.

Voluntary movements are preceded by a temporally flexible preparatory neural process that is present regardless of whether movement is initiated rapidly or thoughtfully.

The novel Reach Cage allows neurophysiology studies of structured behavior with unrestrained Rhesus macaques showing that the frontoparietal reach network is selective for reach goals outside the immediately reachable space.
