To investigate whether a mobile phone exposure might affect snail nociception
29 snails were exposed and 29 snails were sham exposed.
Exposure duration: continuous for 1 h

Comparing the reaction time pattern of each snail before and after exposure, the GSM exposed snails were less sensitive to thermal pain as compared to the sham exposed controls, indicating that radiofrequency exposure induced a significant analgesia.
The study might support earlier findings, describing beneficial effects of electromagnetic field exposure upon nociception.
