Do Touch Signals Stop During Steady Contact?
Steady contact does not silence every touch pathway. Rapidly adapting afferents emphasize changes, while slowly adapting afferents can continue signaling during maintained contact; these response patterns are not the same as conscious attention.

What the illustration shows
A rounded probe indents a dimensional fingertip skin cutaway. A Meissner corpuscle sits within a dermal papilla; a Merkel cell-neurite complex lies at basal epidermis. Two enlarged tissue insets show lamellar cells around a sensory ending and Merkel cells contacted by nerve terminals. Below, the same maintained-contact interval is compared: blue rapidly adapting activity marks cluster at onset and release, while green slowly adapting marks continue during contact. The chart explicitly says teaching symbols, not measured firing rates. Main takeaway: Steady contact does not silence every touch pathway.

How to interpret this poster
- Timing marks are invented teaching symbols, not measured rates, amplitudes or latency.
- Receptor cell counts, shapes and tissue proportions are illustrative rather than verified histology.
- Not an exclusive receptor-to-percept map or a sensory diagnostic test.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
