Description

1. This study examined the ability of pentobarbital to inhibit NMDA and kainate-stimulated [3H]noradrenaline ([3H]NA) overflow in rat brain cortical slices. 2. Pentobarbital inhibited NMDA-evoked [3H]NA overflow at 100 microM and greater and inhibited kainate-evoked [3H]NA overflow at 10 microM and greater. 3. The ability of pentobarbital to inhibit concentration-response curves for NMDA and kainate-evoked overflow of [3H]NA were also examined. Pentobarbital (300 microM) caused a 20% reduction in NMDA and a 50% reduction in kainate-induced maximal responses.
