Group mean ± standard error levels of glutamatergic, serotonergic and dopaminergic neurotransmitters (area/weight) (g−1) in cerebellum of female (top row) and male mice (bottom row) exposed to filtered air (Air; gray shaded area) or Fe nanoparticles (Fe; symbols) measured two days post termination of exposure. (area/weight) (g−1) in cerebellum of female mice (top row) and male mice (bottom row) exposed to filtered air (Air; gray shaded area) or Fe nanoparticles (Fe; symbols) measured two days post termination of exposure. GABA = gamma aminobutyric acid; Gln = glutamine; Glu = glutamate; Tyr = tyrosine; DA = dopamine; DOPAC = 3,4-Dihydroxyphenylacetic acid; HVA = homovanillic acid; NE = norepinephrine; Kyn = kynurenine; Trp = tryptophan; 5HTP = 5-hydroxytryptophan; 5HT = serotonin; 5HIAA = 5-hydroxyindoleacetic acid. * statistically significant at p ≤ 0.05; ~ p value ≤ 0.10
