Reducing subthalamic nucleus (STN) activity has been proposed as an anti-epileptic procedure. Here we show that, on the contrary, a unilateral lesion of the STN causes slight (nonsignificant) increases in the severity of limbic seizures evoked by bicuculline infusion into the piriform cortex, associated with marked Fos expression throughout the cerebral cortex. Abolishing the STN control over the basal ganglia output may therefore play a facilitatory role on cortical activation associated with limbic seizures.
