Research Abstract |
To clarify the pathophysiological role of descending analgesia system in diabetic painful neuropathy, we performed whole-cell patch clamp recordings from rat periaqueductal grey(PAG) neurons. Although the presence of the G protein-coupled, inwardly rectifying potassium current was detected in rat PAG neurons, there was no significant difference in current density between control and diabetic rats. This might be caused by the unstableness of the rat midbrain slice samples, and we need a further arrangement for the improvement of the electrophysiological recording system.
