Effects of EMF chronic exposure and RS on FAMEs in brain regions. a FAMEs saturated/unsaturated ratio. Results are expressed as mean ± SD of 6 animals in each group (*p < 0.05 vs. control group and ^#p < 0.05 vs. RS + EMF group). b Representative total ion chromatogram from each isolated region of rat brain from control group. Fatty acids are shown in order of appearing: palmitic (16:0), oleic (18:1), stearic (18:0), arachidonic (20:4) eicosenoic (20:1), docosahexenoic (22:6) and adrenic (22:4). c Representative total ion chromatogram of fatty acids lipid profile from cerebral cortex on different treatments. d Representative mass spectra of fatty acids obtained by relation mass/charge. Each fatty acid was identified by its specific molecular ion, base peak, and characteristic ions. Palmitic (16:0), oleic (18:1), stearic (18:0), arachidonic (20:4), eicosenoic (20:1), docosahexenoic (22:6), methyl ester
