Six fingers per hand: A congenital additional finger brings motor advantages

Polydactyly is the extraordinary condition of someone being born with more than five fingers or toes. In a case study published in Nature Communications, researchers from the University of Freiburg, Imperial College London, the University Hospital of Lausanne, and EPFL have for the first time examined the motor skills and sensorimotor brain areas in people with polydactyly. The results show that an extra finger can significantly extend the manipulation abilities and skill.

Motor skill learning leads to the increase of planning horizon

We investigated motor skill learning using a path tracking task, where human subjects had to track various curved paths at a constant speed while maintaining the cursor within the path width. Subjects’ accuracy increased with practice, even when tracking novel untrained paths.

Concurrent control of a brain-computer interface and natural overt movements

A primary control signal in brain–computer interfaces (BCIs) have been cortical signals related to movement. However, in cases where natural motor function remains, BCI control signals may interfere with other possibly simultaneous activity for useful ongoing movement. ....
