Neurons in motor cortex contain information about each arm, but these signals are separated into different dimensions, allowing separate control of each arm.

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.
Area 2 of somatosensory cortex represents kinematic details of the entire arm during movement, but this mapping from limb state to neural activity differs for reaching and passive limb displacement.

Plasmodium falciparum aminopeptidase PfA-M17 is essential to parasite survival and plays a role in hemoglobin digestion, providing a rationale for further development of inhibitors against this enzyme.

Plasmodium parasites secrete RhopH2 from the rhoptry organelle into their host red blood cell to facilitate the uptake of essential nutrients required for parasite replication and survival.
An energetic cost related to force rate is quantified in human arm movements, and minimizing this cost predicts smoothness without minimizing variance, unifies motor-planning of smoothness and movement duration, and may help resolve motor redundancies.
