Abstract:
Following electrical stimulation of the tooth pulp, extracellular K+ activity was enhanced by up to 0.1 mM only in the trigeminal motor nucleus which gave a positive slow mass potential (SMP) of low amplitude. No nuclear region giving a positive or negative SMP of high amplitude showed any detectable change. There are possible generation mechanisms of the negative and positive SMP.
