Movement is a Sensory Phenomenon

Sensing is the crucial undercurrent of life, enabling not just grasping a loved one's hand or tying laces, but expressing emotions or creating art. Having evolved since bacterial chemotaxis-a driving force of motility-it's profoundly underrated in movement, often seen as mere byproduct. This article glimpses the evolution of sensing across species, its convergence with motor commands, and deep interdependence. In bionic reconstruction, sensory restoration lags motor advances; we highlight the challenge of translating binary machine signals into the homunculus's stereognostic language, while spotlighting promising biological interfaces pivotal for embodiment of bionic hands.
