  1. N, total number of neurones tested with stimulation at each site; n, number of neurones displaying each of the four types of postsynaptic potential (PSP) or antidromic action potential (AAP), while the % indicates the number of neurones in each of the five classes as a percentage of N. EPSP, excitatory postsynaptic potential; IntV, intertrigeminal area; IPSP, inhibitory postsynaptic potential; mPeriV, medial peritrigeminal area; nPontc, nucleus pontis caudalis; nPontcd, dorsal part of nucleus pontis caudalis; nPontcv, ventral part of nucleus pontis caudalis; nRpc, parvocellular reticular formation; NVmt, trigeminal motor nucleus; NVsnpr, nucleus trigeminal sensorialis principalis; SupV, supratrigeminal area.
