abstract：:Somatostatin is a neuropeptide that in several experimental models of epilepsy has been suggested to modulate epileptic activity. The purpose of the present study was to investigate the role of somatostatin in seizure phenomena. We measured the somatostatin-like immunoreactivity (SLI) by radioimmunoassay of the cister...
