C-Tactile Fibers

Specialized nerve fibers that transmit "affective" touch — slow, gentle stroking linked to well-being and social bonding.

C-tactile (CT) fibers are unmyelinated nerve fibers in the skin that respond to slow, gentle stroking (1–10 cm/s). Unlike fast-conducting touch fibers, CT fibers project to the insula and are linked to emotional and social processing — the "affective" dimension of touch.

Key Functions

  • Affective touch — pleasant, calming, bonding
  • Social touch — grooming, hugging, gentle contact
  • Insula pathway — connects to emotional and interoceptive centers
  • Well-being — CT activation supports parasympathetic tone

In ONDA Life

Part 13 engages "C-tactile fibers and proprioceptive integration to create an ultra-precise body map." These pathways link skin to the brain's well-being centers — essential for sensory expansion and embodiment clarity.
