The Brain and Body Compute Together: Neuromechanics and Sensorimotor Control
summary
Claim: balance and gait emerge from a low‑dimensional library of motor modules rather than single muscle rules. Evidence comes from moving platform perturbations on cats and humans, decerebrate cat locomotion, and Parkinson’s rehab; measurements use EMG + NMF to extract coordination patterns. Surprising finding: each person has consistent, subject‑specific module weights that generalize across standing and walking and change after tango therapy. Timing details matter — reflex (~50 ms), balance correction (~100 ms), strategy change/step (~200 ms) — supporting a hierarchical, embodied control architecture.
