This lecture covers the concepts of touch, proprioception, and cortical representation in kinesthetic and tactile rehabilitation. It discusses cutaneous mechanoreceptors, their types, functions, and neural signals. The lecture also explores psychophysics, including detection thresholds, two-point sensitivity, and spatial acuity of the skin. Additionally, it delves into haptic illusions, sensory substitution technologies for the visually impaired, and the role of somatic feedback in learning arm movements. The presentation concludes with insights on haptic strategies, model predictive control, and the use of exoskeletons in sensorimotor rehabilitation.
