Neither group observed a significant effect of microwave exposure on open field activity. Both groups found changes in variability of the data obtained using the passive avoidance procedure, but not in the same parameters. The U.S. group, but not the USSR group, found significantly less sodium potassium ATPase activity in the microwave-exposed rats compared to the sham exposed rats. Both groups found incidences of statistically significant effects in the power spectral analysis of EEG frequency (but not at the same frequency). The failure of both groups to substantiate the results of the other reinforces the authors contention that such duplicate projects are important and necessary.
