Setup | the mouse was restrained in a plastic restrainer with the murine nose and mid back uncovered for exposure; the tail and paws were placed outside the restrainer. A black MW-absorbing shield was placed between the paw and the restrainer. |
Sham exposure | A sham exposure was conducted. |

The maximum hypoalgesic effect was achieved by exposing to millimeter waves the more densely innervated skin areas (nose and footpad). The effect to the murine back, which is less densely innervated, was not statistically significant. The results support the hypothesis of neural system involvement in the systemic response to millimeter waves.
