Rat foetuses that were exposed to an intermittent hypoxia antenatally exhibited less motor activity and increased levels of anxiety [10]. The specific effects of seizures on the foetuses of rats have been studied in greater detail more recently. Vale and coworkers [11] used a pilocarpine-induced epilepsy model, and found a significant effect on specific hippocampal interneurons in the pups of mothers with epileptic seizures during pregnancy.
