Background/further details
Worms of different strains were distributed in one of the following groups: 1) DECT exposure , 2) DECT sham exposure , 3) WiFi exposure , 4) WiFi sham exposure , 5) GSM exposure and 6) GSM sham exposure . Several tests with different strains (wild type , age- and stress -sensitive strains (DR1572, DR26, TK22 and RB864), model strains for neurodegenerative diseases (NL5901 for Parkinson's disease and CL4176 for Alzheimer's disease ) and GFP -transgenic strains (CL2070, CF1553, SJ4005, LG333, LD1171 and CL2166)) were conducted in the groups. All tests were performed at least twice.
