  1. E excitatory, I inhibitory, Mix inhibitory in one limb and excitatory in other limbs, NR non-responsive to pinch nor contact heat, MDm, MDc, MDl medial, central, and lateral part of the mediodorsal thalamic nucleus, IL intralaminar thalamic nuclei including centrolateral, paracentral, oval paracentral, and central medial thalamic nuclei
  2. aExcitatory units of MDl/IL (95%) was higher than that of MDm/MDc (23%), Z test, p < 0.001
  3. bInhibitory units of MDm/MDc (60%) was higher than that of MDl/IL (1.5%), Z test, p < 0.001
