Direct coupling of haptic signals between hands

摘要: Although motor actions can profoundly affect the perceptual interpretation of sensory inputs, it is not known whether combination and movement signals occurs only for surfaces undergoing or a more general phenomenon. In haptic modality, independent multiple poses challenge to nervous system when combining tactile kinesthetic into coherent percept. When exploring stationary object, come from same hand. Here we probe internal structure by directing two signal streams separate hands: one hand moves but receives no stimulation, while other feels consequences first hand’s remains still. We find that both discrete continuous are combined as if they came This proceeds direct coupling transfer moving feeling hand, rather than assuming displacement mediating object. The due perception inference, because small temporal offset between significantly degrades performance. These results suggest brain simplifies complex coordinate transformation task remapping inputs take account movements body parts in perception, show effects action limited sensors.
