Pleasant touch mediated by Aβ-afferents remains primarily dependent on tactile velocity

This study investigates the role of Aβ-afferents in pleasant touch by comparing vibrotactile and brush stroking, finding that pleasantness follows an inverted-U curve and is influenced by velocity inference.

Tactile Sensitivity to the Frequency Spectrum of Complex Vibrotactile Signals

The study investigates how the frequency spectrum of complex vibrotactile signals affects human perception, finding that missing low-frequency tones are more detectable than higher ones.
