Impaired memory by hippocampal oxidative stress in rats exposed to 900 MHz electromagnetic fields is ameliorated by thymoquinone

Exposed rats: Decreased performance. Increased hippocampal superoxide dismutase, glutathione peroxidase, and malondialdehyde levels. Decreased brain-derived neurotrophic factor level. Decreased N-methyl-D-aspartate receptor expression. Increased gamma-aminobutyric-acid alpha receptor expression.
