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.
