Proprioception allows us to perceive the position of our limbs in space. Neuroscientists from the University of Freiburg have highlighted the key role played by certain neurons in the somatosensory cortex. Published in the journal Nature Communications, these results can be used to develop more efficient neuroprostheses . It's so commonplace that we forget the wonderful complexity of our every move. Picking up a bottle, bringing it to your mouth to drink its contents, even with your eyes closed, presents no difficulty and amazes no one.
