# WEB-030 — 60 GHz: sensory neurons respond differently from direct heating

Why this matters
Sensory nerve endings help an organism detect potentially harmful conditions. In isolated leech neurons, intense millimetre waves changed the threshold for nerve firing differently from direct heating. The experiment offers a mechanism to examine; it does not establish the cause of symptoms in people.

Topic: 60 GHz-region biological responses; Sensory-neuron excitability; Calcium-associated responses

Verification Group: Original text reviewed

Record Role: Original text reviewed

Featured: False

Exposure: 60 GHz continuous wave; approximately 80–170 mW/cm² across the isolated ganglion; acute exposure with substantial heating.

Design: Leech nociceptors; electrophysiology, direct-heating comparison, calcium manipulation and computational modelling.

Finding: Action-potential activation threshold was lower during millimetre-wave exposure than direct heating: 3.9±0.4 versus 8.3±0.4 mV. TRPV1-like receptor sensitisation was proposed.

Statistics: See the original results; effect sizes were not independently recalculated.

Boundary: Intense acute exposure in an isolated invertebrate preparation. Heating rates differed and the probe measured surface, not intracellular, temperature. The molecular explanation is partly model-based.

Protection Question: Which exposure conditions reproduce this finding, and what would establish its relevance beyond the experimental model?

Access: Original methods/results and interpretation reviewed; raw data and supplements were not independently audited.
