The study was designed to replicate a previous study of Lai et al. (publication 109). Rats were exposed to microwave signals identical to those used in the previous study and subsequently tested in a 12-arm radial maze to assess memory performance.
The performance of exposedrats was comparable to that found in sham-exposed or in naive animals (no contact with the exposure system). Regarding the methodological details provided by Lai et al. on their testing protocol, the present results might suggest that the microwave-inducedbehavioral alterations measured by these authors might have had more to do with factors liable to performance bias than with spatial working memory per se.
