Study on Unit Discharges of the Posterior Group of Thalamic Nuclei Evoked by Electric Stimulation of Centromedian Nucleus in Cat
The unit discharges of posterior group of thalamic nuclei (PO)
evoked by stimulating greater splanchnic nerve (SPL)and centromedian nucleus(CM) respectively in cats were studied with extracellular recording method and stereotaxic techniques. The evoked potentials of 63 neurons in PO by stimulating SPL and 16 ones in PO by stimulating CMwere observed in 26 cats
indicating that PO might be one of the representative areas of the splanchnic afferent pathway and there might be a nervous projection between CM and PO. Moreover
convergence of unit discharges produced by stimulating CM and SPL in PO was found
suggesting that pain signals from the viscera and impulses from CM can interact each other at PO.
