2. Do repeated limbic seizures induce depression-like behavior in rats?

It has been reported that rapid kindling of the hippocampus produces lasting depression-like behavior in rats, as evidenced by increased immobility in the forced swim test and a loss of preference for sweetened water (Mazarati et al., 2007). This might suggest that repeated limbic seizure activity could be the cause of the depression often seen in patients with temporal lobe epilepsy.Sixty-day old male Wistar rats were implanted with electrodes in the amygdala and ventral hippocampus and kindled (or sham kindled) daily to a criterion of 10 stage 5 seizures.
