SOD1 and amyotrophic lateral sclerosis: Mutated SOD-1 mouse experimental model (Tg-SOD1G93A), which is currently the most accurate animal model for studying ALS, was employed to assess the possible effects of chronic exposure to ELF-EMFs (2 hours/day, 5 days/week for 7 weeks, to 50 Hz, at 100 and 1000 μT) on the development of this neurodegenerative disease.
