Intraneural sensory feedback to encode objects compliance and shape. a Subjects were implanted with four intraneural electrodes (TIME) in median and ulnar nerves (ME and UE) and were involved in two tasks: intra-digit temporal Dynamic Recognition (DR) and inter-digit Temporal distance Recognition (TR) tasks. In these tasks, the subjects have to recognize stimulation pattern different in temporal-distance and temporal-dynamic. These cues are exploited by subjects in closed-loop to encode objects shape and compliance. b Two active sites eliciting two locally-separated sensations on the phantom hand were considered for both subjects. c Schematic representation of the intraneural stimulation adopted. In DR, the amplitude of the intra-digit neural stimulation was modulated between Smin and Smax being related to the sensation intensity. In TR, the inter-digit temporal distance between two active sites stimulation (multichannel stimulation) was changed. d Induced sensation and stimulation parameters were reported for ME and UE for Subject 1 and 2
