Left mesial temporal sclerosis and verbal memory: a magnetoencephalography study.

The purpose of this study is to examine the pattern of mesial temporal lobe activity in patients with left mesial temporal sclerosis (LMTS) and normal control subjects during a verbal memory task using magnetoencephalography. Six LMTS patients and seven normal control subjects performed a word recognition task while event-related neuromagnetic responses were recorded for 248 trials in each of two runs. An equivalent current dipole model was used to localize activity sources and determine if the right or left mesial temporal lobe was active.

The safety of rapid valproic acid infusion.

Purpose: The recommended rate of administration of valproic acid injection is 20 mg/min. Drug delivery at this rate may be inadequate for expeditious control of seizures. The safety of rapid infusion of valproic acid has not been established, and this study was designed to explore the effects of rapid infusion in patients with acute seizures.
