Intracellular potentials(ICP)of the neurons in PO evoked by stimulating greater splanchnicnerve(GSN)were recorded in 42 cats.The resting potentials and action potentials induced by stimu-lating GSN were 53.74±11.68 mV and 29.44±9.22 mV respectively.Owing to intensity of thestimulation we can record EPSP and single spike or polyspikes on it.The action potentials derivedfrom stimulating GSN(related action potentials)were inhibited by injection of morphine intravenous-ly.On the basis of recording ICP
we also labeled 2 related neurons with stimulation of GSN and 2unrelated ones.Differences between two kinds of the neurons were compared preliminarily.The ICPof the related neuron with stimulating GSN were inhibited by stimulating Amygdala too.Factors influencing amplitute of action potential in intracelluar recording
criteria of determiningnociceptive neuron and inhibition derived from stimulating Amygdala were also discussed.
