The male and female probands (n=55) aged 18 to 45 were daily mobile phone users and with or without symptoms they associated with mobile phone use. The test persons were either exposed or sham exposed. The probands passed seven trials in a virtual spatial navigation task (modeled after the Morris Water Task) in which the participant has to navigate to a platform in a pool.
Modulation type: pulsed
Exposure duration: continuous for 3 h
The group with symptoms improved their performance under exposure to GSM signals, while no such an effect was observed for the group without symptoms. Exposure to GSM signal had no significant effect in both groups on learning in the trials 1 to 7.
