Wolpaw et al. 1989

Macaque monkeys

4-6 yr

6 exposed, 4 sham

3 kV/m, 10 µT; 10 kV/m, 30 µT; 30 kV/m, 90 µT

Well-being, weight, blood chemistry, simple motor tasks, postmortem

No effects

 

Dowman et al. 1989

Macaque monkeys

Adult, 5-7 kg

6 exposed, 4 sham

3 kV/m, 10 µT; 10 kV/m, 30 µT; 30 kV/m, 9 µT

Auditory, visual, somatosensory, evoked response 2 times per week

No effects; only somatosensory decrease in amplitude of late response for 10 kV/m and 30 kV/m

 

Davis et al. 1984

CD-1 mice (male), LAF-1 mice (female)
